在分析研究区生态环境实际问题基础上，提出了生物治理干热河谷区荒坡的对策措施，并对这些措施的治理效益进行了观测、评价．

THE FOREST ENGINEERING TECHNIQUE ON DESERT SLOPE OF DRY HOT VALLEY -Dawazi Countryside in Jiangjia Valley, Dongchuan City For Example

Dawazi desert slope is typical one in dry hot valley, which locates in Xiaojiang basin, the First turbutary of Jinshajing. The desert slope is controled by tubing forest engineering as follows.First, grow the glass by keeping the mountain area to improve microclimate;second,on the basis of the local trees,introduce some other new seeds to grow mixed forest 1 third, improve the forestengineering and land cultivation technique to get more benefit. By the methods above the forest coverage increases from 10% to 70%;the birds increase from 1 to 8 kinds. The amount of dry glass and the moisture cape city increase 3 times;the products on slope land increase 4-6 times;the average income per person increase 4-5 times. As a result the environment is improved and the inhabitants look happy.
