Evaluation of Ecological Effects on the Implementation of Comprehensive Land-use Planning of Zhanjiang City

The implementation of comprehensive land use planning will change land use structure and distribution,and exert a profound influence on the ecological environment.To quantify the influence of the implementation of comprehensive land use planning made on the ecological environment,the ecological effects of the imple-mentation of comprehensive land use planning from 1997 to 2010 in Zhanjiang were quantitatively evaluated from the perspective of ecosystem services value by using the ecosystem services value unit area of Chinese terrestrial ecosystem proposed by Xie et al.As the results shown,from 1996 to 2005,the ecosystem services values of cultivated land,forestland,grassland,residential and mining land,and swampland were decreased,while those of garden land,water area and other unutilized land were increased.From 2006 to 2010,the total value of ecosystem services is to further increased,but it is still to be decreased for cultivated land,forestland,residential and mining land,swampland,which suggests that the whole function of ecosystem services in Zhanjiang was remained to be enhanced,but degradation was also found in some parts of the city.The actual total-value of ecosystem services for 2000 was reduced by 361.66 million Yuan when comparing with the planning value for 2000,and a decrease of 865.15 million Yuan is found for 2010,which indicates that some positive ecological effects have been obtained by the implementation of comprehensive land use planning from 1997 to 2010 for Zhanjiang and the planned objectives were far from to be achieved.Finally,suggestions for strengthening the ecosystem services function in the future revision of land use planning of Zhanjiang are presented.
