摘要:

选择典型干旱区渭干河—库车河三角洲绿洲为研究区,基于遥感、地理信息系统技术和相关应用软件,在详实的野外实测数据、土地利用数据和遥感数据支持下,应用空间插值、叠置分析、逐步回归、神经网络、层次分析等方法,建立评价模型,进行自然、生态、土地利用和综合适宜性评价,相应确定后备耕地资源开发的适宜性等级、适宜度及其分布;提取三期遥感影像信息并进行分类,根据后备耕地资源利用/覆被类型的特征,构建后备耕地资源开发的安全性指数计算模型,加入水源保证条件限制,构建综合安全性评价模型,进行后备耕地资源开发综合安全性的时空分析;基于适宜性与安全性评价,进行叠置分析、综合性分级。研究表明:后备耕地资源开发综合性等级的区域分布呈现环状特征,适合后备耕地资源开发的区域面积与禁止开发的区域面积数量相差十倍。最后提出后备耕地资源开发的举措建议。

Abstract:

Taking the delta oasis of Weigan and Kuqa Rivers as the typical research area, the study established a evaluation model to assess natural, ecological, and comprehensive suitability. The spatial interpolation, superposition analysis, stepwise regression, neural network, hierarchical analysis methods were used based on detailed field data, land use data and remote sensing data. The limiting factor of water source guarantee conditions was added to the newly-establised comprehensive security assessment model. Suitability grades and distribution of the reserve cultivated land resources were determined according to the features of the reserve cultivated land use/land cover types. The spatial and temporal pattern of cultivated land resources were analyzed comprehensively. The findings show that the regional comprehensive development level of the reserve cultivated land resources present a ring-shaped distribution. The area of suitable development of reserve cultivated land resources was ten times than that of prohibition development. Finally, we put forward development proposals and measures of reserve cultivated land resources.

Key words: the reserve cultivated land resources, development, suitability assessment, security assessment, the delta oasis of Weigan and Kuqa Rivers
