Evaluation Of The Ecosystem Service Function Value Of The Dadingzishan Reservoir Area

In this paper,the objective assessment of Dadingzi Mountain reservoir ecosystem value has important significance to protect the ecological environment of Dadingzi Mountain reservoir and the surrounding ecological environment protection and comprehensive utilization is of great significance.In this paper,by using the conditional method reference value method,ecological value method,market value method,shadow engineering method,travel cost method,the results of other methods,Dadingzi Mountain Reservoir material production,flood control,water conservation,water purification,leisure tourism,habitat and ecosystem services for monetary evaluation.Calculation of Dadingzi Mountain reservoir ecosystem service function total value of 4 billion 794 million yuan,is 1.1% of GDP in Harbin city.One of the biggest flood storage value(2 billion 374 million yuan),accounting for the total value of Dadingzi Mountain reservoir ecosystem 49.07%.Followed by the value of water storage function(1.776 billion yuan),accounting for Dadingzishan reservoir ecosystem value of 36.71%.Dadingzishan reservoir service functions to regulate flood storage,water supply main;power generation and ensure shipping and other functions,supplemented by.The calculation of the value of its service function will be conducive to the establishment of ecological and economic accounts in Harbin and provide a scientific reference for the development of the Songhuajiang cascade.
