三峡库区长江防护林模式的研究

Study on the Changjiang Conservation Forest Mode in Three Gorges Reservoir Area

鄂西三峡地区包括秭归、兴山、巴东、夷陵四县(区)。在推广、应用、转化“鄂西山地长江上干流生态经济型防护林体系营建技术研究”科技成果的基础上,通过对坡度的调查,结合气候带、立地条件等因子,划分防护林类型,建立了4种防护林模式类别,11个防护林模式类型,33个模式种类,总结出33个模式种类的关键技术,找出了模式的规律性。

The Three Gorges Reservoir within western H ubei includes four cities of Zigui, Xingshan, Badong, and Yiling. Based on the spread, use, change of the technological effort that the ecological economics conservation forest system built in the former Changjiang River in western of the Hubei Province,through the research of the steep grade with the climate and area condition factors,the four system, eleven mode varies,thirty-three mode form were built. The abstract technology was concluded, and the regularity was found.
