Abstract:

In this paper，the authors chose the ecosystem service value，ecological green equivalent，ecological footprint deficit per capita and comprehensive index of environmental quality as the index system to describe the regional ecological environmental quality，in order to evaluate the efficiency of the input of labour，capital，technology and ecological land use in the process of regional ecological environment protection by using the data envelopment analysis model.It is revealed that the efficiency of ecological environment protection of Suzhou City was in a suitable situation for the last ten years as a whole，30% of the years were effective，20% were effective weakly and 50% useless.The index system of efficiency in useless years was more than 0.97.The reason for the DEA inefficiency of the ecological environment protection in the last five years was due to the lack of ecological land use，and the ecological land became rigid，and thus influenced the regional ecological environment protection.By adjusting the input proportion of factors，all indexes of ecological environment will improve and the regional ecological environment quality will become better.The decline of the efficiency of regional ecological environmental protection is also affected by the population growth，and by the increase of ecological occupancy per capita and the accumulative effect of ecological environment.Finally，in order to promote the coordinated ecological environment protection and socialeconomic development，some suggestions were proposed in this paper.
