摘要

基于遥感和GIS技术，以2000年TM和2007年CBERS影像为主要数据源，分析了渭南8县(市、区)地貌格局及居民地面积的时空变化。分析结果表明:(1)研究区地貌类型复杂多样，山、川、塬、沟壑、沙地和河道兼具，以渭北台塬和渭北沟壑面积最广，比重均超过20%;(2)7a间研究区居民地增加6044.1hm

，其中临渭区增长2718.6hm2，面积变化最多，其次是大荔县，面积增长1057.8hm

，潼关县增长最少，为123.1hm

;研究区居民地单一土地利用动态度(年变化率)均值为2.03%，而各县年变化率以临渭区最高(3.75%)，澄城县最低，仅0.85%。

Abstract

By using remote sensing(RS) and geographic information system(GIS)

the landlorm pattern and the change of residential area of the 8 counties belonging to Weinan City are analyzed based on the TM data in 2000 and CBERS data in 2007. Results show that land form patterns are complex and diversiform with mountain

plain

valley

sandy-land

channel

etcin which the flatland above plain and the valley in the north bank of Weihe River occupy over 20% of the total land area. T he total area of residential sites in all counties increased by 6 044.1 hm2 during the 7 years

in which the biggest is 2 718.6 hm2 in Linwei District

the seeond is 1 057.8 hm2 in Dali County

and the least change is 123. 1 hm2 in Tongguan County.T he d ynam is degree of overall region studied is 2.03%

in which the most one is 3.75%in Linwei District and the least one is 0.85% in Chengcheng County.
