摘要

北方农牧交错带是中国北方农业和畜牧业交错地带

是中国典型的生态脆弱区。选取陕西省北部靖边县为研究区

以1990

2000和2010年3期TM/ETM+影像及社会经济数据为基础

利用土地利用动态度和转移矩阵分析了靖边县1990—2010年土地利用变化及其驱动因素。研究表明:(1)1990—2010年

靖边县林地、建设用地面积呈现增加态势

耕地、草地、水域和未利用地面积为减少态势。(2)1990—2010年

靖边县土地利用变化主要发生于2000年之后

其中尤以建设用地的快速增加为特点。(3)1990—2000年

靖边县耕地、林地和草地之间的相互转变数量较大

且共同向建设用地转变。这种变化主要集中于北部风沙滩区。(4)经济的快速发展尤其是油气等资源的开采是靖边县建设用地变化的主要驱动因素

退耕还林还草等政策的实施

是耕地、林地、草地发生变化的主要驱动因素。

Abstract

The farming-pasturing ecotone in North China is a typical ecological vulnerable zone.Based on thedata obtained from three composite Landsat 5TM/ETM+images of 1990

2000and 2010in Jingbian Countylocated in the north of Shaanxi Province

this paper explores land use change and driving foctors in the transitional zone by land use change degree and transition matrix.Results show that:(1)Woodland and buildingland increased from 1990to 2010

whereas cropland

grassland

water area and unused land decreased.(2)The land use change in Jingbian County mainly occurred after 2000year

especially the rapid change of building land from 1990to 2010.(3)The amount of transformed land among cropland

woodland and grasslandwas larger and the three land use types were mostly changed into building land

which mainly occurred in thenorthern suburb area of Jingbian County from 1990to 2010.(4)Rapid economic development

especially theexploitation of oil and gas resources

were the main driving factors for the change of building land

while theimplementation of the returning farmland to forestland/grassland project was the main driving factor for thechanges of cropland

woodland and grassland.
