Assessment of and Controlling Strategies for Ecological Risks of Land Consolidation Based on Ecosystem Services

Ecological risk assessment and management of land consolidation are two objective requirements of the sustainable development of land resources under the background of ecological civilization. During the 13th Five-year Plan period, land consolidation will increase in investment and scale, which will not only bring about positive effects on regional social and economic development, but also have profound impacts on structure and functions of regional ecosystems. How to monitor and control ecological risks has become an issue causing more and more attention. On the basis of systematic elaboration of the connotation and characteristics of ecological risks of the land consolidation, analysis was done of ecological risk factors and evaluation index system relative to ecological effect of land consolidation, and thereof, a new idea was brought forth about identification, assessment and control of ecological risks based on full-process analysis of land consolidation projects, including ecosystem service functions as an important content of ecological risk assessment. Thus the limitation of the researches in the past on ecological risk has been overcome with more emphases on changes in structure and functions of an ecosystem. Scientific issues and development trend that need more attention in tackling ecological risks of land consolidation are pinpointed.
