摘要

以张家口市1996—2008年的土地利用变更调查数据为基础

采用土地利用变化贡献率、土地利用动态度、信息熵、优势度、均衡度、集中化、多样化等方法和模型

对张家口市土地利用结构特征及其动态变化进行了系统分析。结果表明:(1)耕地、林地、草地、未利用地4种土地利用类型占张家口市土地面积的92%左右

构成张家口市土地利用结构的基本格局。(2)1996—2008年

张家口市耕地和未利用地大幅度减少

林地、园地、草地、居民点及工矿用地、交通用地均在增加;各土地利用类型的动态度依次为:林地>耕地>园地>未利用地>交通用地>草地>居民点及工矿用地>水域。(3)土地利用结构信息熵、均衡度呈增加趋势

优势度指数呈减小趋势

土地利用结构向无序、均衡化方向演变。(4)土地利用结构集中化指数减小

多样化指数增大

表明张家口市土地利用结构趋于多样化。

Abstract

Based on the detailed survey data of landuse change from 1996to 2008in Zhangjiakou City

many models and methods including the contribution rate of landuse change

dynamic degree of landuse change

information entropy

equilibrium degree

degree of dominance

diversification and centrality degree were used to analyze the landuse structure characteristics and its dynamic change.Results show that:(1)The main landuse types in Zhangjiakou City were arable land

forestland

grassland and unutilized land

which accounted for about 92% of the total land area.(2)The landuse change was obvious in the city from 1996to 2008.The areas of arable land

unutilized land and water body had a drastic reduction

while the areas of forestland

orchard

grassland

construction land and traffic land increased.In terms of the maximum dynamic degree of landuse change

the landuse types from high to low were in the order of forestland

arable land

orchard

unutilized land

traffic land

grassland

construction land and water body.(3)The informationentropy

equilibrium degree of land use for Zhangjiakou City increased

while the degree of dominance decreased

which indicated that land use structure was changing to be disordered and equalization.(4)The centrality degree of landuse increased along with the diversification decreased

which shows that the landuse structure of Zhangjiakou City tended to be diversified.
