湖北省森林资源动态变化分析与评价

Analysis and Evaluation on Dynamic Changes of Forest Resources in Hubei Province

为科学地进行湖北省森林资源生态效益的监测,合理地评价和经营森林资源,根据中国科学院地理科学与资源研究所提供的中国自然资源数据,以及湖北省林业勘察设计院多次对湖北省森林资源清查的数据,从森林资源面积、蓄积量、组成结构等方面总结分析了34年来森林资源动态变化的原因。研究表明,20世纪60年代中期至80年代中期,林业用地面积和蓄积均呈下降趋势,其后,由于湖北省政府及林业部门的高度重视,实施一系列林业生态保护与可持续发展工程,如"十年绿化湖北"、国家"长防林工程"、"平原绿化工程"等,湖北省森林资源自1985年以来持续稳定增长,为湖北省生态安全的构建发挥了积极的作用。

For scientifically monitoring the ecology benefit of forest resources, reasonably evaluating and managing forest resources in Hubei Province, according to Chinese Natural Resources Database and forest data collected by the Institute of Forestry Survey and Design of Hubei Province, this paper provided detailed information about 34 years dynamic changes of forest resources and concisely explained the factors resulting these changes from the area of forest resources, the amount of growing stock, the structure and other aspects. The results showed that Hubei＇ s forest resources decreased rapidly from the mid-1960＇s to mid-1980＇s, but since 1985 ,they have steadily increased. Hubei Provincial government and forestry departments have attached great importance to the implementation of a series of forestry, ecological protection and sustainable development projects, such as the ＂Decade Green Hubei project＂, ＂Yangtse protection forest project,＂ ＂Plain greening project. ＂ In this way, Hubei forest resources sustained and grew stably, and promoted the ecological safety.
