土壤发育与地形密切相关,而在土壤发育过程中不同的地形就会对耕地有效土层厚度、灌溉条件和植被产生一系列的重要影响,根据莎车县的地形与土壤形成的关系将莎车县地形概括为5种类型,分别为冲积洪积扇上、中、下部,沙漠边缘,山前洪积平原;依据专家评定出对莎车县耕地地力影响比较大的12个因素和耕地地力评价系统,以不同地形部位的尺度对莎车县耕地地力质量等级划分的影响进行系统分析,明确制约因素,提出更有效的改良利用措施,为提升莎车县耕地高效利用提供科学依据。
Soil development is closely related to the terrain, and different terrains will have a series of important impacts on the effective soil layer thickness, irrigation conditions and vegetation in the process of soil development. According to the relationship between the topography and soil formation of Shache County, The topography of the county is summarized into five types, namely, the upper, middle and lower parts of the alluvial-alluvial fan, the edge of the desert, and the alluvial plain before the piedmont. According to experts’ assessment, 12 factors that have a great influence on the cultivated land fertility of Shache County and the evaluation of cultivated land productivity System to systematically analyze the impact of different landform scales on the division of cultivated land quality in Shache County, define the restrictive factors, propose more effective measures for improvement and utilization, and provide a scientific basis for enhancing the efficient utilization of cultivated land in Shache County.
