鄂西山区坡耕地分布格局与环境因子的关系
|
摘要
本文在Arc GIS分析的基础上,通过典范对应分析鄂西山区土地利用的分布,特别是坡耕地的分布和环境因子的关系,结果表明不同环境因子对不同土地利用耕地类型的影响程度存在明显差异,对土地利用及耕地格局重要性影响比较大的因子主要是人口密度、坡度。分析土地利用及耕地类型与各环境因子关系得到对土地利用,特别是鄂西山区坡耕地格局影响较大的环境因子,为土地利用格局优化和农业结构调整提供了参考依据。
Based on Arc GIS and canonical correspond analysis,it was studied the land use pattern in the mountainous areas of western part of Hubei Province,especially focusing on the relationship between slope arable land distribution pattern and environmental factors. The results show that different environmental factors have the obvious differences in the impact to the different arable land use types. The main factors having the important impact to the land use and arable land pattern are population density and slope,respectively. The analysis on the relationship between land use and arable land types and environmental factors,especially the main factors having the important impact to the slope arable land in the mountainous areas of western part of Hubei Province,will provide the reference for the optimism of the land use pattern and the adjustment of the agriculture structure.
