利用1995年和2000年TM卫星影像资料和马尔柯夫链的理论,分析了三峡库区土地利用变化的特点和演变趋势,结果表明,在未来的5～10年内,三峡库区土地利用非农化速率减少,但占用农地面积仍然较大,农业用地结构不合理.

By using the landsat TM datd of 1995 and 2000 and Markov model,some features of land use changes in the Three Gorges Reservoir Region during the 5 years were analyzed,and the evolution trend of the land use change were predicted.The result showed that in the coming 5～10 years the agricultural land was changed into non-agricultural construction land became slow down to some extent,the agricultural land area taken up by non-agricultural construction was still big.the agricultural la...
