Ecological Compensation of Dongjiang River Basin Based on Evaluation of Ecosystem Service Value

Ecological compensation is conducive to coordinating the relationship between regional economic development and ecological environment protection. The equivalence factor method was used to evaluate the ecosystem service value of Dongjiang River Basin and the equivalent weight table of ecosystem service value of Dongjiang River Basin was conducted. Furthermore, according to the benefit range of ecosystem service function, the theoretical ecological compensation standard of Dongjiang River Basin was determined. Finally, the ecological compensation priority sequence (ECPS) was introduced to determine the urgency of ecological compensation in 19 counties and cities along Dongjiang River Basin and the ecological compensation standard of each county and city of Dongjiang River Basin was investigated. The results show that the total value of ecosystem services in Dongjiang River Basin is 171.141 billion yuan, in which the forest ecosystem value accounted for 86.17% of the total value. The regulating service is the most important function in the first ecological service types, and the hydrological regulation is the most significant function in secondary ecological service types. The total theoretical value of ecological compensation of Dongjiang River Basin is 104.726 billion yuan, in which the forest ecosystem compensation value is 88.021 billion yuan, accounting for 84.05% of the total compensation value. The forest ecosystem compensation value is the core of regional ecological compensation. The actual total amount of ecological compensation of 19 counties and cities of Dongjiang River Basin is 6.873 billion yuan, of which the amount for Dongyuan County is the highest at 1.676 billion yuan. The priority order of ecological compensation of 19 counties and cities in Dongjiang River Basin is Dongyuan > Anyuan > Xunwu > Zijin > Xinfeng > Lianping > Longchuan > Heping > Dingnan > Longmen > Xingning > Huidong > Boluo > Huiyang > Heyuan > Huizhou > Zengcheng > Dongguan > Shenzhen.
