长江中游生态经济型防浪林体系结构优化模式的研究

AN OPTIMUM FOREST STRUETURE FOR EC0-ECONOMIC WAVEBREAK SYSTEM IN THE MIDDLE REACHES OF THE YANGTZE RIVER

对长江中游防浪林进行了详细调查，以防浪林数量化防浪指数、防浪林消浪效果、防浪林落淤效果、林木生长过程、平台高程、气候土壤条件、生态环境以及经济效益分析为依据，研究了乔、灌、草相结合的立体防浪体系，制定了生态经济型防浪林体系结构优化模式。

Based on the survey data on the wavebreak forest in the middle reaches of the Yangtze River ,the quantitative wavebreak index table for wavebreak forest,the wave decreasing effect table the sediment effect table the stand growth process table and systematic analyses of climate,soil,ecological environment and economic effect,the cubic forest structure of wavebreak system combining“arbor-shrub-herb”were made and the optimum forest structure for“Eco-economic”wavebreak system was worked out. The studies provided scientific basis for the silviculture of new generation of wavebreak forest.
