Evaluation on the service function of River Dalinghe ecosystem based on ecological water requirement
摘要
Abstract
At present the research about evaluation on the service function of river ecosystem all did not consider the problem of river's ecological water requirement. If the river's inflow can not reach river's ecological water requirement, the service function of river ecosystem will not normal to play. Based on the classification of the service function of River Dalinghe ecosystem, market value method, cost substitution method and opportunity cost method were used in the calculation in this paper, and river's ecological water requirement was considered in the calculation of the water supply function value, the storage water function value, and the sediment transport function value, and the other function also realized on the basis of it. The results showed that: the direct using value is 9.264 billion yuan per year, the indirect using value is 21.517 billion yuan per year, the total value is 30.781 billion yuan per year. Through the analysis, concluded that the core service function of River Dalinghe ecosystem is functioned water function, aquatic products function and habitat function. It should be given full play to the core function and taken the other function into account.关键词
