【摘要】 森林资源是地球生态系统发生发展的产物,也是地球生态系统的重要组成部分,更是人类赖以生存的物质基础,同时森林资源也是数量与质量的统一体,量与质的保证是森林资源发挥多种效益的基础。本文从森林资源管理的角度和林业可持续发展的角度对森林资源质量相关问题进行分析和研究,深入理解森林资源质量的内涵,建立森林资源质量评价指标体系并对森林资源质量进行评价。科学评价森林资源质量,为森林资源可持续经营提供科学依据,对发挥森林资源的最大效益和指导森林资源经营管理具有重要的意义。本文对森林资源质量的研究现状和进展进行了综述,在已有的研究基础上,提出了主要的研究对象和研究内容,围绕森林资源质量评价问题,以可持续发展为指导思想,辨析森林资源质量的概念,分析其内涵及影响森林资源质量的主要因素,建立了既适宜在系统中进行行量化计算,又能够充分反应森林资源质量的森林资源质量评价指标体系。指标体系涵盖了四层、六个方面的指标,包括森林生产力、森林结构、森林健康、生态服务效能、经济服务效能和社会文化服务效能。借鉴相关领域的研究,提出并实现了综合指数法、模糊综合评价法、集对分析法、神经网络法和物元分析法在森林资源质量评价中的应用。以1999年湖北省通山县和嘉鱼县二类森林资源调查数据以及林业数据为研究案例,运用综合指数法对通山县进行森林资源质量评价,其综合指数为0.738,结果为良。运用模糊综合评价法、集对分析法、神经网络法和物元分析法分别分析通山县森林资源质量,结果是一致的,并且与综合指数法结果一致。五种方法对嘉鱼县的评价结果也是一致的。结合信息时代下森林资源管理的模式,利用林业信息技术,在理论研究的基础上,实现了森林资源质量综合评价信息系统。该系统功能包括指标数据管理、指标体系生成、指标分类管理、指标权重计算、综合指数法模块、模糊综合评价法模块、集对分析法模块、神经网络法模块及物元分析法模块。系统的实现为快速决策、决策的科学化提供了支持,也为森林资源决策管理提供了必要的基础。更多还原

【Abstract】 Forest resource is a product which developed with development of the earth’s ecosystem; it is also an important component of the earth’s ecosystem and is the material basis of human survival. The guarantee of quantity and quality is the basis for a variety of benefits of forest resources. In this paper, the questions related to forest resources is analyzed and researched from the perspective of forest resources monitoring, forest resources management and forest sustainable development. The purpose of this paper is to understand the content of forest resources quality deeply, to establish the evaluation index system of forest resources quality and to evaluate forest resources quality. Scientific evaluation of forest resources quality provides foundation of forest resources sustainable management and it plays a very important role in bringing maximum benefit of forest resources and guiding management of forest resources.In this paper, the status and progress of forest resources quality study were reviewed, and based on these researches, main research content is proposed. Around the issue of forest resources quality evaluation, based on the guiding ideology of sustainable development, the concept of forest resources quality is analyzed, the main impact factors of forest resources quality is discussed, and a forest resources quality evaluation index system is established which could calculate in the system and could able to fully reflect the quality of forest resources. The forest resources quality evaluation system contains four covers and six aspects of indicators, which includes forest productivity, forest structure, forest health, ecological services,.economic and social services and cultural services.Drawing on related research in the field, Composite index method; fuzzy comprehensive evaluation method; neural network method; matter-element analysis method and set-pair analysis method was proposed and achieved in forest resources quality evaluation. Inventory data of tongshan country and jiayu country in Hubei province and other forestry data were used as example in this research; five kinds of method could implicate in forest resources quality. The evaluation result of five methods obtained in line.Under the combination of the information age of forest resources management Patten, based on the theoretical study, using forestry information technology, a evaluation information system of forest resources quality was achieve. The system functions include data management of indicators, reference value management, and indicators classification management, weight calculator of indicators, Composite index method module; fuzzy comprehensive evaluation method module; neural network method module; matter-element analysis method module and set-pair analysis method module. This system provides support and necessary foundation for scientific forest resources management decision-making.更多还原
