The Urban Forest Benefit Evaluation of CHANGSHA-ZHUZHOU-XIANGTAN Urban Agglomeration

According to the features of CHANGSHA-ZHUZHOU-XIANGTAN urban zone, this paper establishes an evaluation index system on urban forest benefit with Delphi method and some other mathematical models, then evaluates its urban forest benefits by this system, and concludes that ChangZhuTan area urban forest earns 2717210.22 × 10⁴ Yuan in which the ecological value is 1944328.76 × 10⁴ Yuan, the social value is 628799.27 × 10⁴ Yuan, the economic value is 144082.18 × 10⁴ Yuan. At last the analysis of evaluation results is given to provide some theoretical and scientific foundations for the construction of “two-oriented society” in CHANGSHA-ZHUZHOU-XIANGTAN urban area.
