Abstract: As one of the five ethnic corridors in China, the Zang-Qiang-Yi corridor is a historical witness to the interaction and exchange among Zang, Qiang, Yi, and other ethnic minorities in southwest China. However, the spatial scope of the corridor has not been clearly defined. This study preliminarily defines the spatial scope of the Zang-Qiang-Yi corridor by considering the natural geographical conditions and human characteristics, and constructing the ethnic minority cultural exchange index as the key index for scope identification. The study uses multiple sources of data, such as basic geographical information, intangible cultural heritage distribution, and national population census, to develop the spatial scope of Zang-Qiang-Yi corridor Dataset. Results show that the spatial scope of the Zang-Qiang-Yi corridor includes 162 county-level administrative regions, involving 25 cities and states in Sichuan province, Yunnan province, Guizhou province, Xizang autonomous region, and Qinghai province. The dataset includes boundary data of the corridor, population proportion of ethnic minorities in the counties (cities) of the corridor, distribution of intangible cultural heritage, and ethnic minority cultural exchange index data. The dataset is archived in. shp and. xlsx formats, consisting of 9 data files, with data size of 4.05 MB (compressed to 1 file, 2.54 MB).

1 Introduction

The Zang-Qiang-Yi corridor is an ethnographic concept referrings to the migration corridor of the Zang-Qiang-Yi system in western China, which is dominated by the ancestors of many ethnic groups from the Zang-Qiang-Yi system, running through the great northwest and southwest of China[1]. In 1978, Mr. FEI Xiaotong proposed the concept of ??Tibetan-Yi corridor??, which scholars have enriched to ??Zang-Qiang-Yi corridor?? in recent years, considering the important historical position of Qiang people in the region[2–4]. The region is dominated by high mountains and valleys, with many layers of mountains and rivers flowing, and is one of the most complex and diverse natural ecological regions in China. The frequent migratory flows and extensive cultural exchanges of many ethnic groups since the pre-Qin dynasty have made the cultural complexity and diversity of this region outstanding[5], and it is one of the five important ethnic corridors in China[6]. The Zang-Qiang-Yi corridor is a vivid portrayal of the pluralistic pattern of the Chinese nation, and the in-depth study of the ??Zang-Qiang-Yi corridor?? is of great importance for promoting the construction of the common spiritual home of the Chinese nation and cultural self-confidence and self- improvement.

In-depth research is necessary to clarify the spatial scope of the Zang-Qiang-Yi corridor. Although most scholars use the corridor in the Six Rivers basin and the Hengduan Mountains as the spatial scope of the Zang-Qiang-Yi corridor[7,8], many inconsistencies are observed between these scopes and the Zang-Qiang-Yi corridor in terms of ethnic and cultural concepts[1]. The Zang-Qiang-Yi cultural industry corridor, delineated by the Ministry of Culture, Sichuan province, and relevant cities and states, considers administrative divisions and industrial bases, and belongs to the concept of economic zones. Therefore, the lack of a clear definition of the spatial scope of the Zang-Qiang-Yi corridor, the failure to consider the natural geographical conditions and human characteristics, and the lack of refinement to the county level, make it difficult to guide the formulation of relevant ethnic cultural development policies.

This paper constructs the ethnic minority cultural exchange index based on multiple sources of geographic, ethnic, and cultural data, integrates physical geography and human characteristics, and uses county-level administrative districts as the basic unit to identify the spatial scope of the ??Zang-Qiang-Yi corridor?? through threshold selection. Thus, the Boundary data of Zang-Qiang-Yi corridor is developed. This dataset can provide necessary data support for ethnographic and sociological research and policy formulation related to ethnic and cultural development in the Zang-Qiang-Yi corridor.

were obtained from the 2020 China Population Census Subcounty Information. The ICH flow distribution data were obtained from the spatial distribution data set of five batches of national ICH in China The ICH distribution data were mainly based on the ICH lists in[11], and the frequency of ICH distribution in each county-level[12] administrative region was obtained by querying its distribution range on the China ICH website[1].

3.2 Methodology

The spatial scope of the Zang-Qiang-Yi corridor was determined by referring to the spatial scope of the Six Rivers basin and the Hengduan Mountains and a review of related literature to identify the county-level administrative regions involved in the physical geography of the Zang-Qiang-Yi corridor[13]. To quantitatively measure the core human characteristics of the Zang-Qiang-Yi corridor as a region with extensive minority cultural exchange, this study constructed the ethnic minority cultural exchange index (EMCEI) as a key indicator to define its spatial scope, calculated as

                                                                                                                   (1)

where Pi and Ni are the proportion of minority population and the frequency of ICH distribution in county-level administrative region i, respectively. For county-level administrative region i within the Zang-Qiang-Yi corridor, the proportion of minority population is higher than that of the whole country and at least one ICH dissemination is observed, that is, , .

3.3 Technology Route

The data development process for this study (Figure 1) involved three main steps. First, a preliminary selection was made for the county-level administrative districts involved in the physical geography of the Zang-Qiang-Yi corridor based on the 2021 county-level administrative divisions of China, the scope of the Hengduan Mountains, and the scope of the Six River basin. The ethnic minority cultural exchange index of each county-level administrative district in the preliminary selection area was then calculated by using the percentage of minority population and the frequency of ICH flow in 2020 by county. Finally, the range of values and relevant literature were combined to define the spatial scope of the Zang-Qiang-Yi corridor with reasonable thresholds.

4 Data Results and Validation

4.1 Data Composition

The research obtained three sets of spatial data files (.shp format) and 1 statistical data table (.xlsx format). The three sets of spatial data files were boundary data of the Zang-Qiang-Yi corridor, boundary data of the Liujiang River basin, and boundary data of the Hengduan Mountains. The statistical data table included the proportion of ethnic minority population in the counties (cities) of the Zang-Qiang-Yi corridor, the data of the distribution of ICH, and the ethnic minority cultural exchange index data. Although the data of the Liujiang River basin and Hengduan Mountains are correct, they are irrelevant to the ultimate purpose of the study. Therefore, only the boundary data and statistical data tables of the Zang-Qiang-Yi corridor were retained in the final dataset, which will be published later.

4.2 Data Products

The Six Rivers basin involves 33 cities and states in Sichuan, Yunnan, Qinghai, and Xizang autonomous regions, including 228 county-level administrative districts, covering all county-level administrative districts involved in the Hengduan Mountains. Therefore, the natural geographical area of the Zang-Qiang-Yi corridor is the area of the Six Rivers basin, which is also the primary area for the ethnic minority cultural exchange index calculation in this study (Figures 2 and 3). In this region, the population ratio of ethnic minorities is spatially distributed with high values in the northwest and low values in the southeast, and its boundary is relatively consistent with the HU Huanyong line (Figure 4). The frequency of ICH distribution is characterized by high value areas and low value areas, reflecting the diversity and complexity of culture in this region (Figure 5). The high value area of the  ethnic minority cultural exchange index is relatively consistent with the range of the Hengduan Mountains, whereas the areas downstream of major rivers, such as the Jinsha and Min rivers, which are dominated by Han culture (e.g., most of the districts and counties under Chengdu, Meishan, and Yibin), are low value areas (Figure 6).

The scope of the Zang-Qiang-Yi corridor was identified by using 0.2 as the threshold of  ethnic minority cultural exchange index and combining the requirement of spatial distribution contiguity (Figure 7). This range includes 161 county-level administrative regions, involving 25 cities and states in Sichuan, Yunnan, Guizhou, Xizang autonomous region, and Qinghai provinces (Table 2).

4.3 Data Validation

Comparing the scope of the Zang-Qiang-Yi corridor identified in this study with the scope of the Zang-Qiang-Yi cultural industry corridor in the published ??Zang-Qiang-Yi cultural industry corridor master plan??, the major cities and states involved are more consistent with the core areas in the ??Zang-Qiang-Yi cultural industry corridor master plan??. Considering that the scope of the Zang-Qiang-Yi cultural industry corridor master plan focuses more on the development conditions of cultural industries and the smallest delineated unit is the city and state, the scope of the Zang-Qiang-Yi corridor identified in this study can be considered more scientific and reasonable.

5 Discussion and Conclusion

The Zang-Qiang-Yi corridor is an important ethnic cultural area in southwest China, but its spatial scope definition is still controversial in academic circles. This study considers the physical geographic conditions and human characteristics of the region, and based on multiple sources of data, such as basic geographic information, ICH distribution, and national population census. The spatial scope of the Zang-Qiang-Yi corridor is identified by constructing the ethnic minority cultural exchange index and setting thresholds on the basis of the initial selection of the physical geographic scope. The identified Zang-Qiang-Yi corridor includes 162 county-level administrative regions, involving 25 cities and states in Sichuan, Yunnan, Guizhou, Xizang autonomous region, and Qinghai provinces, which is more consistent with the scope of the core area of the Zang-Qiang-Yi cultural industry corridor in the Zang-Qiang-Yi cultural industry corridor master plan. This study is an exploration of the application of integrating multisource data for ethnographic and sociological research, and innovatively constructs the ethnic minority cultural exchange index, which has certain implications for related research. The developed spatial scope dataset of the Zang-Qiang-Yi corridor can provide necessary basic data for the research on the Zang-Qiang-Yi corridor and support the formulation of policies related to cultural industries in the region.

However, the Zang-Qiang-Yi corridor is dynamic in nature, and the scope identified in this study is the current spatial boundary obtained by taking county-level administrative districts as the basic division unit. In addition, the ethnic minority cultural exchange index constructed in this study only considers the proportion of minority populations and the frequency of ICH distribution, Future research can further enrich the spatial scope identification and zoning research results of the Zang-Qiang-Yi corridor by including more humanistic elements, such as major ancient road (channel) networks, language (dialect) areas, traditional villages, and archaeological relics.
