摘要

Desertification distribution in Nanchuan region of Chongqing City is studied on the basis of 2004 TM and maps of geology, hydro meteorology and landuse. According to the development of desertification and the distribution of the deserts, it is suggested that the gentle land (<5°) be used as paddy field by protective tillage and green food production land; and the gentle slope land (5°～15°) be used as cultivation and plantation areas; the relatively dip slope (15°～25°) as vine (honeysuckle) planting land, fruit planting land and ecologic grass land; the steep slope land (>25°) as water conservation forest and scenery forest by long term close hillsides to facilitate afforestation.
