中文摘要: |
本文探讨了一种定量确定湿地保护范围的方法。首先根据区域地形地貌和水环境等自然条件初选数个可能的湿地保护规模的方案,然后计算各方案表征社会经济、生态环境和水环境条件的6个特征指标:湿地初级生产力产值、淹没投资、环境影响指标、蓄滞洪水量、湿地补水难度系数和湿地水体更新难度系数。最后采用灰色系统关联度法和权重图解法量化确定整体效益相对最佳的湿地保护规模的方案。文中以吉林省查干湖湿地为例进行了计算,取得了较符合实际的计算结果。 |
英文摘要: |
A quantitative method for determining the protected extent of wetland is proposed. First several schemes of protected extent should be drafted according to the regional geography, topography, meteorology, water environment and natural conditions. Then, 6 indexes including primary productivity, investment for submerge, environmental impact, flood detention, difficulty coefficient of water supply and difficulty coefficient of water renew for each scheme are calculated. Finally, the correlation degree method for gray system and weight graphic method are applied to quantitatively determine the suitable scheme having the most comprehensive advantage. An example is given. |
