1990～2012年北部湾经济区土地利用程度变化分析

摘要

Based on analysis of land use structure in Beibuwan Economic Region from 1990~2012, the models of land use degree and land use degree change are used to analyze the characteristics of the spatial-temporal distribution and regional differences in 15 countries. The result shows that the degree of land use was more significant, creasing by 43.22, but there is no major change happening to the distribution patter of 15 countries. The land use degree changed and rate of change were both greater than zero and the land use was in the evolution period. Under the constraints of natural conditions, there is biggish difference in the spatial distribution of land use degree in Beibuwan Economic Region.%通过对1990～2012年北部湾经济区土地利用结构的变化分析，运用土地利用程度指数模型以及土地利用程度变化模型统计了各地区土地利用程度的时空变化特征及其区域差异。结果表明，1990～2012年北部湾经济区土地利用程度大幅度提升，增加了43.22个百分点，但土地利用程度分布格局并未发生太大变化；土地利用程度变化量及其变化率均大于0，土地利用处于发展期；在自然条件的限制下，区域内部土地利用程度差异较大。
