区域森林景观资源承载力评价方法的探讨——以江西省婺源县为例

Evaluation method of regional forest landscape carrying capacity—A case study of Wuyuan County,Jiangxi Province

  • 摘要: 通过对森林景观资源承载力内涵及其特点的探讨,提出以承载指数(承载量/承载力)评价森林景观资源的承载状态。采用理论分析和专家咨询相结合的方法,构建由经济、生态和游憩3个层次共15个指标组成的森林景观资源承载力评价指标体系,建立承载指数计算模型。并以江西省婺源县为例,应用层次分析法确定指标权重,明确各指标的计算方法,对该区域森林景观资源承载力进行了计算。结果表明,研究区域综合森林景观资源承载指数为0.3559,森林景观资源总体上处于弱载状态,生态和游憩承载指数更低,分别为0.2308和0.2448;经济承载量接近满载,承载指数达0.9710。调减对森林景观资源的经济需求是提高研究区森林景观资源综合承载力的关键,而控制能源性消耗和加强果木林发展是提高综合承载力的主要措施。

     

    Abstract: Based on the connotation and characteristics of forest landscape resource carrying capacity,a carrying index(ratio of carrying quantity to carrying capacity) method was postulated to evaluate the carrying capacity of forest landscape resources.An evaluation index system involving 15 indices of economy,ecology and recreation, was set up by means of theoretical analysis and expert best-judgment method,to establish a carrying index calculation model for forest landscape resources.The carrying capacity of forest landscape resources of Wuyuan County,Jiangxi Province was evaluated based on the above established method.Index weight was determined by analytic hierarchy rocess,and the calculation method of the indices was explicited.The overall carrying index of the forest landscape resources as calculated by the evaluation method is 0.3559,indicating that the forest landscape resources are in a state of weak loading.Ecological and recreational carrying indexes are 0.2308 and 0.2448 respectively,revealing a weaker state of loading. However, economic carrying capacity is about saturated,as reflected in the carrying index value of 0.9710.The results indicate that decreasing economic demand on forest landscape resources is a key factor to improve the overall forest landscape resources carrying capacity.A main approach achieving this goal is by decreasing energy consumption and enhancing fruit forest cultivation.
