宝鸡市金渭两区土地利用变化及驱动力分析

Analysis of the Land Use Change and Driving Forces in Jintai and Weibin Districts of Baoji City

根据1988、2000、2004年3期宝鸡市TM遥感影像,利用遥感技术和地理信息系统空间分析方法,研究了1988～2004年宝鸡市金渭两区的土地利用动态变化情况。结果表明,1988～2004年宝鸡市金渭两区耕地面积迅速减少,园地面积迅速增加,同时居民点及工矿用地也有较大幅度的增加,林地呈现减少趋势,而未利用地有增加趋势,水域面积变化不大。在分析基础上,从人口、政策、经济和城市化等因素方面揭示了其社会经济驱动机制。

According to the TM remote sensing images in 1988,2000 and 2004,dynamic change situation of land use in Jintai and Weibin Districts of Baoji City in 1988-2004 were studied by using spatial analytical methods of geographical information system and remote sensing technology.Result showed that farmland area decreased rapidly in Jintai and Weibin Districts of Baoji City from 1988 to 2004,while the garden land increased greatly.At the same time,residential area and industrial and mining land use enhanced in a great deal.Woodland showed reducing tendency and unused land had the trend of enlarged.Water area had little changes.On the basis of analysis,socioeconomic driving mechanism was revealed from the factors including population,policy and urbanization.
