Analysis of Land Use Patterns and Temporal Changes in Hilly Region of Northwest Hebei Based on Terrain Gradient——A Case Study of Huailai County in Hebei Province
摘要
Abstract
In order to explore the evolution law of land use pattern in different terrains of hilly regions,and to clarify the function of natural and human factors to land use change,we took Huailai County as an example to examine the spatial and temporal variation characteristics of land use change in different terrains during the period from 1993 to 2013 by using the topographic index and distribution index based on the spatial analysis technology of RS and ArcGIS.The results show that the spatial distribution and the change situation of the six land use types were all influenced by the topographic factor.Dominant position in water area mainly distributed in the regions with elevation of 300~500 m,the slope was 0°~6° and the terrain level was second level;the construction land and cultivated land distributed in the regions with elevation of 500~700 m,the slope was 0°~6° and the terrain level was first level;the terrain adaptability of garden plot was better than cultivated land,whose distribution regions were wider than cultivated land;forest and unused land mainly distributed in the regions with the elevation above 900 m and slope above 6°,and forest had advantage in a higher level of terrain.These results can provide basis and guidance for the reasonable use and scientific planning of the land resources in Huailai County,which means a lot for the sustainable development.关键词
