基于土壤和地形约束的耕地识别方法研究——以锦西灌区为例
Cultivated land identification based on soil properties and terrain features identification: A case study of Jinxi irrigation area
摘要
Abstract
Cultivated land resource identification is one of the most important technology to guarantee the safety of food strategy.Based on existing research,from the aspects of precipitation,productivity of cultivated land,potentiality of grain production and quality of cultivated land,a new model based on soil property and terrain features is presented to identify cultivated land resource in Jinxi irrigation area.The model is presented on the platform of ArcGIS.The results show that:Of the total 1 200.59 km2,568.334 km2 is the most suitable for cultivation;5.92 km2 is more suitable to cultivate;The area of cultivated land reaches 564.15 km2 after revision and the rest do not fit cultivate.By taking account of two features,the cultivated land is about 62.19 km2.Compared to traditional methods,the new model is more comprehensive,objective and precise.关键词
