秦岭自然保护区群成本效益研究(III)——综合效益评价

Cost-Benefit Analysis for the Qinling Mountain Nature Reserve Group:Evaluation of Comprehensive Benefits

根据秦岭自然保护区群成本效益的计量结果,如何评价秦岭自然保护区群的综合效益是本文研究的关键问题。本文选用了模糊数学隶属函数法,结合秦岭自然保护区群三大效益的计量指标体系及计量结果,进一步筛选出17个主要的综合效益评价指标,同时按照评价指标体系对七大保护区的截面数据进行了估算。研究结果表明,秦岭自然保护区群中周至保护区和太白山的综合效益发展是最好的,佛坪、长青、牛背梁以及朱鹮自然保护区次之,相对综合效益发展最差的是天华山保护区。本研究总结出一套适合森林类型的自然保护区综合效益的评价指标体系与评价方法,可以在缺乏时间序列数据的情况下,利用横向截面数据了解目前自然保护区综合效益发展的情况,并为自然保护区生物多样性的保护提供科学依据。

Comprehensive benefit evaluation is the basis for nature reserve resource management and planning,and important in territorial planning.We evaluated nature reserve comprehensive benefits（1） to understand the operation and management of a nature reserve system,especially the harmonious development of the nature reserve with surrounding areas,and（2） provide a basis for the optimization of protection policy.Cost benefit evaluation takes the measurement as the foundation,and considers the whole reserve operation status,and the influence of the cost and benefit on regional development.We used the method of horizontal comparative analysis,involving the transverse comparison of nature reserves within the study area.Through the same time evaluation of the comprehensive benefit between them,we determined the optimal scheme and solved deficiencies in nature reserve development.We selected a fuzzy mathematics method and combined this with a measurement index system and measurement results for three major benefits across the Qinling Mountains nature reserve group.We chose 17 leading comprehensive benefit evaluation indexes and estimated the section data of seven large reserves according to the evaluation index system.We found that that comprehensive benefits of Zhouzhi Nature Reserve and Taibai Nature Reserve were best;the benefits of Foping,Changqing,Niuliangbei and Crested Ibis Nature Reserve were second;and the benefits of Tianhua Mountain Nature Reserve were lowest.This study summarized a suitable comprehensive benefit evaluation index system and evaluation method for forests of different types,which,when lacking time series data,can use section data to evaluate the comprehensive benefits of nature reserves and support nature reserve optimization.
