资阳市土地利用生态系统服务功能价值评估 总被引:1,自引:0,他引:1
《技术与市场》2014,(10)
土地利用总体规划会改变用地结构,用地结构变化会影响区域的生态环境,对规划期间各种土地进行生态系统服务价值评估,可以对生态环境的变化做一个量化的对比,能提升规划的决策水平,确保规划的生态环境导向性。运用生态系统服务功能价值法对资阳市土地利用总体规划进行环境影响评估,得出规划对资阳市以后的环境发展的影响为正,但人口过快增长导致环境压力过大状态,并给出一些优化资阳市的土地利用和生态环境的措施建议。 相似文献

以岳阳市为研究对象,在分析其土地利用与生态环境现状的基础上,结合土地利用总体规划,分析规划期内的主要环境影响要素,利用指标综合评价法分析、评价土地利用规划对岳阳市带来的环境影响。评价结果表明:岳阳市土地利用规划的实施对当地生态环境起到了明显的改善作用;2010年现状评分低于2010年规划评分,表明岳阳市目前环境状况与规划预期相比仍有差距。 相似文献

According to the structure-based forest management theory,the appraisal indices system of natural forest management efficiency was established from spatial utilization,species diversity, constructive species competition and tree composition,which could be used to depict stand status,and its metewand was given.Relative weight was endowed by The Analytic Hierarchy Process (AHP),and then the conception of natural forest management efficiency comprehensive appraisal index was put forward for the first time and applied to four different sampling plots of natural forest, three of them from Dongdapo forest region,Jiaohe, Jilin province,and one from Baihua forest area, Xiaolongshan,Gansu province,China.The results are as following:the stand status was obviously improved after being managed and plot A,B got a mark of "medium" while C and D were "perfect". From high to low,the arrangement of forest management efficiency comprehensive appraisal index was C>D>A>B.This appraisal result abided by the phenomenon detected in the practical field.The forest management efficiency comprehensive appraisal index brought up in this paper could be taken as a way of comprehensive quantitative change of stand state which directly reflects the effort of forest management and affords scientific basis of natural forest management effort. 相似文献

根据结构化森林经营理论,从描述林分状态的空间利用程度、物种多样性、建群种竞争态势和林分组成等4个方面构建了天然林经营效果评价指标体系并给出了相应的评价标准。运用层次分析法确定权重,在此基础上提出了天然林经营效果综合评价指数的概念,并将其应用于吉林蛟河市东大坡林区(包括A、B、C共3块样地)和甘肃小陇山百花林场(D样地)天然林经营评价。结果表明:经营后林分状态明显改善,A、B样地经营效果等级为"中",C、D经营效果等级为"好",按经营效果综合评价指数从高到低排列为C>D>A>B,评价结果与林地中实际观察到的现象一致。本文提出的经营效果综合评价指数是林分状态综合量化的一种表达方式,能够直观简洁地反应出经营效果,可为天然林经营评价提供科学依据。 相似文献

ABSTRACTDespite the growing body of research on ecosystem services and their valuation, Jordan still faces many challenges with integration of ecosystem service concepts into forest sustainability policy and management planning. One major challenge is the incorporation of local communities into policy design, planning, and implementation. This article aims to provide information about the social value of forests’ provisioning and cultural services in a spatial context using Geographical Information Systems (GIS). The study utilizes a new approach to mapping value in rural areas by projecting local forest value from interview data. A value index is created based on indicated importance of services as well as proximity to households, permitting interpolation of value in forested areas between survey points. The resulting maps illustrate ecosystem service “hotspot” areas of significance to planning and management. This mapping technique can be applied in other locations where homes are situated near and within the ecosystems being assessed. The resulting maps serve to inform forest management policy and planning by better integrating communities’ preferences into development and conservation efforts, ensuring more efficient utilization of ecosystem services. 相似文献
