传统的地下水开采潜力评价方法主要采用单个指标进行评价,难以全面科学地反映地下水开采潜力的影响要素。地下水的空间分布、动态变化受到经济社会发展、开采技术等多个因素影响,也与自身调节有关,这与生态位理论的观念吻合。文中提出... 传统的地下水开采潜力评价方法主要采用单个指标进行评价,难以全面科学地反映地下水开采潜力的影响要素。地下水的空间分布、动态变化受到经济社会发展、开采技术等多个因素影响,也与自身调节有关,这与生态位理论的观念吻合。文中提出地下水生态位的定义、计算公式;对河北平原9个主要城市进行地下水生态位计算、聚类分析,分析其地下水开采潜力;并与传统方法的评价结果进行对比。结果表明:除保定、秦皇岛和廊坊外,其他城市的两种方法的评价结果大致相似;差异分析说明地下水生态位的评价方法更全面、科学合理且符合实际。生态位理论将为地下水开采潜力评价分析提供一种新的、甚至是根本性的尝试。 展开更多

Based on the groundwater resources evaluation, the groundwater exploitation potentiality evaluation is aiming at providing references for management, planning and development of groundwater. Traditional evaluation methods mainly adopted individual indicator as a method which cannot fully reflect the affecting factors of the groundwater exploitation potential in a scientific way. The idea that the spatial distribution and dynamic change of groundwater is not only affected by socio-economic development and exploitation technology but also influenced by its regulation is coincided with the niche theory. This paper has preliminarily applied the niche theory to groundwater exploitation potential analysis, and proposed the concept of groundwater niche as well as its related definition, connotation and calculation formula. Meanwhile, by taking the Hebei Plain as an example, the article has made an evaluation of groundwater exploitation potentiality and a contrast with the results of the traditional evaluation methods on the construction of groundwater niche index system, and then verified the feasibility and rationality of this index system. It turns out that, it is truly comprehensive, scientific and rational to make groundwater niche calculation and exploitation potential analysis by using the evaluation index system. Niche theory has provided a new and fundamental attempt for the analysis and competition strategy for the groundwater exploitation potentiality evaluation. 展开更多
