运用层次分析法从林分质量、立地条件、林分生态功能和森林抵抗力4个方面来构建残次林评价指标体系,并以福寿林场杉木残次林为研究对象,对其进行了残次水平等级评价。最后确定杉木残次林4个准则层评价指标权重分别为:林分质量(0.542 3)... 运用层次分析法从林分质量、立地条件、林分生态功能和森林抵抗力4个方面来构建残次林评价指标体系,并以福寿林场杉木残次林为研究对象,对其进行了残次水平等级评价。最后确定杉木残次林4个准则层评价指标权重分别为:林分质量(0.542 3)、林分立地条件(0.233 3)、林分生态功能(0.139 7)、林分抵抗力(0.084 7)。在福寿国营林场随机选取6块杉木残次林进行评价,其中重度残次林分5块,轻度残次林分1块,结果表明,建立的残次林评价指标体系能够比较客观的反应残次林的质量状况,为残次林的改造,林分质量和林分生态功能的提高提供科技支撑。 展开更多

The Irtysh River Basin refers to a water conservation area and a vital ecological barrier in Xinjiang and also partially in Central Asia.Here,the technical solution for the ecological protection and the restoration of the Mountains-Rivers-Forests-Farmlands-Lakes-Grasslands system(MRFFLGs)pilot project in the Irtysh River Basin is refined,by complying with the core concept,i.e.,"mountains,rivers,forests,farmlands,lakes and grasslands are a community of life".The solution stresses the specific characteristics of ecologically protecting and restoring MRFFLGs in the Irtysh River Basin,which aim to reduce ecological water use,soil erosion,forest and grassland degradation,the ecological destruction of mines,water environment pollution and other issues.With overall protection,system restoration,district policy,and problem orientation as the overarching ideas,162 sub-items of 44 major items with seven categories have been designed and implemented in the project.In addition,some highlights of the management experience that are worth promoting when the pilot project is being implemented are also summarized(e.g.,the use of laws to solve historical problems,scientific argumentation and third-party evaluation,proactive guidance for the engagement of people,modern information technology support,and integration with local sustainable development).Lastly,four policy suggestions are proposed:(1)Building a model of systematic protection and restoration by using basins as the basic geographic unit;(2)Establishing and optimizing key weak links of systems and mechanisms;(3)Focusing on remedying the shortcomings of regional talents,technology and capital;and(4)Promoting the MRFFLGs project to integrate"industry,city,people,and tourism"for carrying out a large-scale system project. 展开更多
