[Integrated evaluation of eco-agricultural practices in Deqing County, Zhejiang Province].

Integrated index method was used to evaluate the practices of eco-agriculture in Deqing County in 1990-1998. The results showed that the integrated benefit, resources use, and ecological, economic and social benefits appeared a rising trend. The value of integrated benefit index in 1998 was 2.36 times of that in 1990. The benefit index, however, also fluctuated in these years, which meant that the eco-agricultural system of Deqing County still had some problems to be resolved. Adjusting industry structure in rural areas, lessening pollution produced by rural industry, and improving stability of eco-agricultural system should be highlighted in the next stage.
