摘要: 以新疆维吾尔自治区叶城县为例,将国土空间开发模拟为生态保护和国土开发两个过程,运用最小累积阻力模型和空间分析方法构建叶城县国土空间开发适宜性评价体系。结果表明,叶城县国土开发适宜区总面积为27 359.86 km2,生态保护适宜区总面积为968.84 km2,整体呈中心发散、带状分布的格局,并将叶城县域划定为生态保护区(占比81.79%)、保护开发区(占比14.79%)、开发保护区(占比2.78%)和开发建设区(占比0.64%)。运用最小累积阻力模型进行国土空间开发适宜性评价可更贴近干旱区县域客观实情。干旱区生态环境脆弱,国土空间开发工作对生态环境影响大,应持续推进生态文明建设工作,提高国土空间开发质量,落实耕地保护并进行土地改良,加强区域生态环境保护和修复,不断优化开发格局,推动适宜性评价、适宜区功能与规划建设相适应。

Abstract: Taking Yecheng County in Xinjiang as an example,the land space development was simulated as two processes of ecological protection and land development,and the minimum cumulative resistance model and spatial analysis method were used to construct the Yecheng County land space development suitability evaluation system. The results showed that the total area of Yecheng County suitable for land development was 27 359.86 km2, and the total area suitable for ecological protection was 968.84 km2,showing a centrally divergent and zonal distribution pattern on the whole; Yecheng County was divided into ecological protection zones(81.79%), protected development zones(14.79%), development protected zones(2.78%) and development and construction zones(0.64%). Using the minimum cumulative resistance model to evaluate the suitability of land and space development could be closer to the objective reality of arid counties. The ecological environment in arid areas was fragile, and the development of land space had a great impact on the ecological environment. In the future, it should be continued to promote the construction of ecological civilization, improve the quality of land space development, implement cultivated land protection and land improvement,strengthen regional ecological environment protection and restoration, continuously optimize development patterns,promote suitability evaluation, and adapt the functions of suitable areas to the planning and construction.

Key words: ecological priority, arid counties, land and space development, suitability evaluation, Yecheng County
