摘 要:基于可行性、科学性、系统性原则,以环境、社会、经济、美学和绿化等5项为约束层指标,结合灰色统计法和专家决策信息建立了具有24项标准层指标的评价体系,对北京平原百万亩造林工程建设效果进行了综合评价,其中环境指标最为重要,权重为0.461 4,美学指标的权重最低,仅为0.115 2。评价总得分为72.38分,这一得分与刚进行3a造林绿化的客观实际基本吻合。本文同时结合该评价结果对北京城市平原工程造林建设提出了建议。The effectiveness evaluation index system was built based on the principle of being feasible, scien- tific and systematic. Every indicator was selected by grey system statistical method and expert decision- making information. The built evaluation system contained 5 constrained layer indicators., environmental, social,economic, aesthetic, greening indices, and 24 index level indicators. Among all the indicators, the most important indicator was environmental index, its weight was 0. 461 4% the least important indicator was aesthetic index,its weight was 0. 115 2. The test area was evaluated by the built evaluation index sys- tem with a score of 72.38. The score fit the fact that the afforstine construction began 3 years ago. The e- valuation results would provide theoretical references for the urban forestry and its development.
