北方农林牧交错带土地利用空间结构调整研究——以内蒙古阿荣旗为例

选择北方农林牧交错带中的典型区域———内蒙古阿荣旗为研究案例,经对1∶10万土地利用现状图、土壤分布图、土壤侵蚀图、1∶5万地形图及有关统计资料等源数据的分析,发现土地利用现状与土地适宜性评价结果差异极大。以土地适宜性评价结果为主要依据并结合该旗实情,对土地利用结构进行合理化调整。用聚类分析方法构建了由耕地型、农林结合型和林牧结合型土地利用区组成的土地利用区划方案,并分别指出各土地利用类型区的开发利用方向与措施。

Study on Spatial Structure Adjustment of Land Use in the Northeast--A Case Study in Arong county of Inner Mongolia

This paperchooses a typicalarea-Arong county of Inner Mongolia in the interlock zone ofagriculture,forestryand livestock farmingin the northeastof China as a study case.Through the analyses of the present mapof 1∶100,000 land use the map of soil distribution,the map of soil erosionand the 1∶50,000 topographic map,and the statistical yearbook 2000,this research found out the present land use is very different comparing to the result of suitable evaluation.Mainly based on the result of land use suitability evaluation,integrating with the fact,this research adjustsspatialstructure of land use reasonably.In the end,we planed the types of land usewith the method of analogyanalysis and pointed out the development directionof land exploitation types,which provides scientific basis of specialstructure adjustment for the area and a set of method systemfor the interlock zone of agriculture,forestryand livestock farming of spatialstructure adjustment of land use.
