Abstract

Abstract: Using the comprehensive evaluation indexes system of chinese ecological forest engineering,we evaluated the benefit of 77 countoies' form Yangtze River protection forest engineering (the first period)in Sichuan and Chongqing. The comprehensive benefit is 6 times more so far, and 9 times more by 2010 than1986 (the starting time).Furthermore, suggestions on forestst and structure adjustment of every branch of Yangtze River and on the new foundation of Yangtze River Shelter Forest in Sichuan and Chongqing were put forward.

Key words: Hydrological scale, Scaling
