APPLICATION OF ECOSYSTEM SERVICES VALUATION IN ENVIRONMENTAL IMPACT ASSESSMENT FOR LAND-USE PLANNING——TAKING DAQING CITY AS AN EXAMPLE

The environmental impact assessment(EIA)is now widely used in the evaluation of policies,plans and strategies.Land use planning is very important because of its role in land2use and land2coverchange(LUCC) which can lead to ecosystem and environmental change.In this article,the value of ecosystem services was used as an assessment index for conducting an environmental impact assessment of Daqing land use planning.The Chinese ecosystem services value per unit area for different ecosystem types was used to calculate the total value of ecosystem services in Daqing.The value increased from 373.71×108 yuan in 1996 to 787.07×108 yuan in 2010.During the planning period,all the single value of ecosystem service,especially waste disposal and climate regulation and water maintenanc,increased.This is becaused of increase of area of woodlands and water.Then,we took into account the population explosion of Daqing in recent years.The per capita ecosystem services value was calculated and the results show that the total ecosystem services value increased,the value per capita also increased,from 15 302.99 yuan in 1996 to 28 097.57 yuan in 2010.When compared with population growth,the growth rate of ecosystem services value was much faster,and the development of economy and ecological environment were coordinated.The accuracy of ecosystem services valuation plays an important role in the EIA for land-use planning.The land-use planning improved ecological environment of daqing city in order to achieve purpose of the ecological environment protection
