Priority evluation of the agroforest landscape management of the upper reaches of Min River

Ten influencing factors of agroforest landscape management were identified and classified into four classes based on their characteristics. Using the EMDS(Ecosystem Management Decision Support system) model embed in ARCGIS9.x platform, the priorities of all of the influencing factors were analyzed with assessment knowledge-base that was built by NetWeaver based on fuzzy logic theory. The results show that 1) in the integrity assessment of feasibility factors, four sub-watersheds, i.e., ws3, ws6, ws8 and ws9, are low priorities, the others six sub-watersheds are in moderate priorities; 2) in the integrity assessment of efficiency factors, the priorities of ws1, ws9 and ws10 are strongly supported, however ws8 is low supported. The other sub-watersheds are moderately supported; 3) The priorities analyses for landscape of all sub-watersheds are low supported except ws1-ws3, which are strongly supported; 4) The final assessment for all of the influencing factors show that all of the sub-watersheds are in the moderate support priorities except ws8, which is low priority.
