Emergy analysis of the wetland comprehensive development level

摘要

As the wetland ecosystem in the field of research is insufficient, this paper established Effect Evaluation Index System of comprehensive development level of wetlands based on their ecosystem functions and performance characteristics. The entropy method was used to determine the index weight, the set of integrated analysis was used to measure the level of development of wetlands, and the East Juyan Lake was used as a practical example. The results showed that comprehensive development level of East Juyan Lake wetland presented a trend of decreased first and then increased, However in the vertical perspective, the overall comprehensive development level of the wetland was low, which was consistent with theoretical study and system function evaluation of East Juyan Lake basin. This research has great significance to both improving the theoretical research in the field of wetlands and accelerating scientific understanding of the importance of delivering Heihe water to East Juyan Lake basin.
