Evaluation on Ecological Effects of Implementation of Comprehensive Land Use Planning in Bohai New Area in Cangzhou City

[Objective]The objective of this study is to evaluate the impacts of the comprehensive land use planning on the ecological environment in order to prevent and alleviate the adverse environmental impacts during the project implementation processes.[Methods]The Bohai new area in Cangzhou City of Hebei Provine was selected as the study area.Based on the land use planning data and the existed land use data from2009 to 2013,the ecosystem service value assessment method was used,and the sensitivity index and grey prediction models were employed.The changes in land use and ecosystem service value were analyzed from2009 to 2013in the study area.The value of ecosystem service in the year of 2015 and 2020was predicted,and compared with the planning data.[Results](1)From 2009 to 2013,the area of the construction land has greatly exceeded the total area of the planned construction land,and the ecosystem service value decreased by1.11×10~7 yuan.This indicated that economic benefits were overemphasized,whereas the ecological benefits were neglected during the project implementation processes.(2)The prediction results showed that the ecosystem service values were expected to be reduced by 7.08×10~7 in 2020 and the ecosystem service function in the study area were expected to be weakened.[Conclusion]The local government should pay more attention on the eco-environment degeneration issues during the project implementation processes,and take positive and effective measures to improve the relationship between economic development and eco-environment protection.
