重庆渝东北地区水土保持乔木及大径竹类植物调查及评价

Investigation and Evaluation of Soil and Water Conservation Trees and Large Diameter Bamboos Plants in Northeastern Chongqing

以重庆渝东北地区水土保持乔木及大径竹类植物为研究对象,采用层次分析法,从环境适应性、生长状况、水土保持效果、经济价值等方面,构建评价指标体系,对渝东北地区水土保持乔木及大径竹类植物筛选及评价研究,结果表明渝东北地区水土保持乔木及大径竹类植物资源丰富,47科122属231种。根据重庆渝东北地区水土保持乔木/大径竹综合评价得分及排序,共有3级以上(分值>80分)水土保持植物87种,其中Ⅰ级水土保持植物共31种,Ⅱ级水土保持植物共31种,Ⅲ级水土保持植物共25种。重庆市水土保持植物资源非常丰富,有很多资源尤其是药用植物资源需要开展一些基础研究,研究开发其利用价值,攻克其产业化的关键技术,依靠科技创新,培育新型产业,为渝东北地区水土保持林建设提供理论依据及技术支撑。

The environmental adaptability,growth status,soil and water conservation effect,economic value,and other aspects of soil and water conservation tree and large-diameter bamboo plants in northeastern Chongqing were studied by using the analytic hierarchy process to screen and evaluate these plants.Results showed that the plant resources of soil and water conservation tree and large-diameter bamboo in northeastern Chongqing were abundant with 231 species of 122 genera in 47 families.According to the comprehensive evaluation index and ranking of soil and water conservation trees and large diameter bamboos in northeastern Chongqing,this region included 87 species of soil and water conservation plants(index>80),including 31 species of plants that perform best in soil and water conservation,31 species of plants that perform better in soil and water conservation,and 25 species of plants that perform general in soil and water conservation.The water and soil conservation plant resources in Chongqing were very rich.For many resources,especially medicinal plant resources,we should carry out some basic research to develop their utilization value and overcome the key technologies of their industrialization,relying on scientific and technological innovation to cultivate new industries.This could provide theoretical foundation and technical support for the construction of soil and water conservation forests in northeastern Chongqing.
