Journal of Northeast Agricultural University(English Edition) 2012年第3期19卷 87-91页

作者： qiao li-fang Zhang Yi-chuan Qi An-guo li Xin-zheng School of Horticulture and Landscape Architecture Henan Institute of Science and TechnologyXinxiang 453003HenanChina

Classifying and ranking the huge amounts of landscape planning works of urban wetland park is always difficult due to the multi-functions （ecological, leisure, educational and disaster prevention） of the urban wetland park. Therefore, an optimizing rank system is urgently needed. Analytic Hierarchy Process （AHP） and Technique for Order Preference by Similarity to Ideal Solution （TOPSIS） models were used to rank the planning works of 30 urban wetland park based on four mainly factors, which included landscape ecological planning, landscape planning, ecological planning and economic planning. The study indicated that the AHP- TOPSIS model had good discrimination in the classification and ranking of landscape planning works of urban wetland park and it was also applicable to the planning works of other urban greenbelts.
