Abstract:
Objectives To represent the distribution of geomorphological values in Xinjiang and to identify key protection areas. To this end, an evaluation system for the spatial distribution of geomorphological resource value in Xinjiang, China has been constructed. The resulting system will provide a scientific basis and decision-making support for the zoning planning of Xinjiang national parks.
Methods Based on an analysis of the existing literature and the current evaluation system, this study proposed seven evaluation indexes for geomorphic resources in Xinjiang. The relative weights of each index were determined using the AHP and Delphi methods, and different evaluation methods were developed for quantifiable and unquantifiable indicators, in accordance with the characteristics of the indexes. Subsequently, a GIS-based weighted analysis was conducted to derive the evaluation results for the distribution of geomorphic resource value, utilizing the assigned weights and scores for each indicator.
Results The results demonstrated that the regions exhibiting high geomorphic resource potential were distributed through the southeastern portion of the Kunlun potential area. The middle-high geomorphic resources were scattered in the eastern part of the potential area. The regions of geomorphic resources were scattered in the east of the potential area. The regions with low geomorphic resources are distributed in the west of the potential area.
Conclusions The evaluation results derived in this study can display the spatial distribution of geomorphic resources in Xinjiang in a more intuitive and comprehensive manner, and provide basic data for the construction of potential areas of Xinjiang National Park. The evaluation system constructed in this study can be conducive to supporting the site selection, planning, and protection project design of Xinjiang National Park, thereby ensuring the high-quality construction and development of the park. Simultaneously, the evaluation system constructed in this study can provide methodological references for the evaluation of geomorphic resources in other regions of Xinjiang, facilitating the broadening of research and application of geomorphic resources.
