An Assessment of the Rational Range of Eco-Compensation Standards: A Case Study in the Nujiang Prefecture, Southwestern China

Eco-compensation is an effective means of coordinating ecological protection and economic development, the assessment its standards core content in study eco-compensation projects. To improve operability standards, taking Nujiang Prefecture as area, we combine equivalent factor method water footprint to evaluate ecosystem-service-value (ESV) spillover use market comparison calculate opportunity cost. The final upper lower limits model constructed on basis ESV results show following: (1) has been effective, based stabilization after initial increase. main types ecosystem services provided are regulation provision services. Gongshan County makes most significant contribution total ESV. (2) ratio self-consumption shows a trend first rising then falling. This mainly explained through reduction industrial agricultural water. After deducting method, it can be observed that there Prefecture. (3) cost increases yearly from 2005 2020 owing policies. Combined with spillover, determined rational range standard between CNY 6.17 × 102 million 120.01 2005, 10.02 128.25 2010, 30.34 197.12 2015, 41.97 227.52 2020. current offer decision makers more flexible while contradiction regional development.
