- Title:
- Preliminary Study on Ecological Water Use in Yanchi County of Ningxia
- Keywords:
- ecological water use; Classification of ecological water use; calculating of ecological water use; Yanchi county
- 分类号:
- X171.1;S157
- 摘要:
- 根据生态学的基本理论，依据生态系统的基本组成，提出了生态用水的定义，建立了生态用水的分类系统，并进一步根据盐池县的实际情况，对当地生态用水类型进行界定。计算得出了盐池县各项生态用水类型的用水量，结果为森林植被生态用水6.05×108 m3/a，水土保持生态用水0.19×108 m3/a，草地建设生态用水8.18×108 m3/a，湖泊洼地生态用水0.062 7×108 m3/a，城镇绿化生态用水0.003 1×108 m3/a。
- Abstract:
- Based on the basic ecological theories, the authors present the definition of ecological water use and established the system of ecological water use classification according to the basic constitute of ecosystem, and further classified local ecological water types according to the practical condition of Yanchi County.The calculating result on every kinds of ecological water are the following:the average annual ecological water use of forest cover is 6.05×108 m3/a; the average annual ecological water use of soil and water conservation is 0.19×108 m3/a; the average annual ecological water use of meadow cultivating is 8.18×108 m3/a; the average annual ecological water use of lake and billabong is 0.062 7×108 m3/a; the average annual ecological water use of plantation in the town is 0.003 1×108 m3/a.
