【摘要】：本文認為某些生態(tài)因子具有瓶頸特性,一旦它們的評價值超過敏感閾值,對應地段的生態(tài)敏感性就會急劇提高,而不論其他因子的評價結果,本文稱這類因子為生態(tài)瓶頸因子。據(jù)此,本文根據(jù)變權理論,提出了生態(tài)瓶頸因子優(yōu)先的變權綜合評價模型和評價指標體系,它在綜合多個因子評價結果過程中,對超過敏感閾值的瓶頸因子會動態(tài)增加其權重以保證這些敏感地段在最終評價結果中得以體現(xiàn),從而反映出瓶頸因子的作用,同時又在一定程度上綜合了其他生態(tài)因子的效果,評價結果更為合理。最后,以毗鄰湖北網(wǎng)湖濕地省級自然保護區(qū)的陶港鎮(zhèn)為例進行了實證研究。
[Abstract]:This paper holds that some ecological factors have the characteristic of bottleneck, once their evaluation value exceeds the sensitive threshold, the ecological sensitivity of the corresponding location will increase sharply, and this kind of factor is called ecological bottleneck factor regardless of the evaluation results of other factors. According to the theory of variable weight, this paper puts forward a comprehensive evaluation model and index system of ecological bottleneck factor priority, which is used in the process of synthesizing the results of multiple factors evaluation. The bottleneck factors over the sensitive threshold will dynamically increase their weights to ensure that these sensitive areas are reflected in the final evaluation results, thus reflecting the role of the bottleneck factors, and at the same time synthesizing the effects of other ecological factors to a certain extent. The evaluation results are more reasonable. Finally, a case study of Taogang Town, which is adjacent to the provincial nature reserve of Wanghu wetland in Hubei Province, is carried out.
