摘要
Land use and protection has become a global hot spot.How to use land resources is an important topic forthe future socio-economic sustainable development.This paper analyzes the land use changes of Mata lake of Shan-dong province in China,from 1985's to 2000's using multi-temporal remotely sensed data including TM in the 1985s,ETM+in the 2000s and ancillary data such as soil use map,water map etc.The remote sensing imageries were cali-brated,registered and geo-referenced,then classified by multi-source information data and remote sensing image in-terpretation expert system based on knowledge base.Five land use types were extracted from remote sensing image-ries,that is,water body,agriculture land,rural settlement,bare land and none-use land.The total precision is 80.7%and Kappa index is 0.825.The analysis result of the remote sensing shows that during the past 15 years,water re-source dropped off very promptly from 51.77 km~2 to 16.65 km~2 and bare land reduced greatly more than 60% inMata lake region.With the development of the economy and agriculture areas,more and more water body and bareland converted to agriculture land use and rural settlement areas.Since last years,the Mata lake has been affected bynatural factor,human activity and increasing population.So its land use pattern greatly changed from 1985 to 2000.The information of land use changes provided scientific supports for land planning and environmental protection.
