摘要
以阿克苏地区新和县为例,基于ArcGIS和SPSS软件,对影响新和县耕地综合质量的所有评价单元进行空间属性赋值。采用了特尔斐法及文献阅读法来赋值影响新和县耕地综合质量各评价因素的权重。通过回归分析法,建立了耕地减少率与距离因素的4种关系模型,进一步分析了新和县各区位因素、各乡(镇)耕地立地条件的优劣状况。在LESA计算方法下,定性与定量相结合地分析了新和县耕地利用的社会经济条件以及耕地自然质量优劣。最后,根据计算值,将新和县耕地分为4个等级,3种类型。
Taking Xinhe County in Aksu area as an example,we evaluated the spatial attributes of all evaluation units affecting the comprehensive quality of cultivated land in Xinhe County based on ArcGIS and SPSS software.Delphi method and literature reading method were used to assign the weight of each evaluation factor affecting the comprehensive quality of cultivated land in Xinhe County.By means of regression analysis,four relationship models of cultivated land reduction rate and distance factors were established,and the advantages and disadvantages of cultivated land site conditions in Xinhe County and each township(town)were further analyzed.Under the LESA calculation method,the social and economic conditions and natural quality of cultivated land in Xinhe County were analyzed qualitatively and quantitatively.Finally,according to the calculated value,Xinhe County farmland was divided into four grades and three types.
