西藏尼洋河流域果树资源及其开发途径探讨

The fruit tree resources of Niyang River Basin of Xizang are rich. The artificial fruit trees consist of 9 species and more than 90 varieties,such as apple (Malus pumila),pear(Pyrus) ,peach ( Prunus persica (L. ) Batsch), plum (Prunus spp. ) .apricot (Prunus armeniaca) and grape (Vitis virifera). Wild fruit trees consist of 7 families, 16 genera and 41 species. At present,the utilization of these resources are at a low level. There arc great potentialities for development.This paper gives some ways of utilization of the fruit trees in the area. On the basin between Cirab Commune and Pai Commune of the lower reaches of Niyang River and Yarlungzangbo River,the fresh fruit trees and dried fruit plantation areas in "Y "shape should be developed into a production base of fruits (dried fruits )of Xizang. The existed orchards should be fully utilized and fruit processing factories should be established in order to meet the need of fruits on the market of Xizang.
