摘要： 利用GIS手段,运用环境经济学评价方法对莫莫格自然保护区潜在土壤养分效益进行估算,同时对潜在土壤养分效益的空间分异进行探析。结果表明,莫莫格自然保护区湿地潜在土壤养分效益为153×108元,保护区单位面积潜在土壤养分效益为10.6×104元·hm-2;其中,中部湿地潜在土壤养分的效益为12.7×104元·hm-2,东部为12.2×104元·hm-2,西部为7.6×104元·hm-2,即中部>东部>西部。在湿地土壤养分中,有机质、全钾对潜在土壤效益的贡献率大,而全氮、全磷的贡献率最低。潜在土壤养分效益估算及其空间分异研究,弥补了湿地效益评估的空白;同时为湿地的恢复重建、湿地管理提供了必要的理论依据。

Abstract: Wetland has many functions and attributes,such as mitigating flood,regulating climate, preventing erosion,providing latent soil nutrient and species habitat and so on.Wetland benefits comprise functions,purposes and attribute,they can be calculated by direct value,indirect value and non-use value of wetland ecosystem.Based on GIS and evaluation means of environmental economy,estimation has been done on latent soil nutrient benefit of Melmeg Nature Reserve,at the same time,its spatial variation has been studied.The results showed latent nutrient benefit of Melmeg Reserve was 153×108 yuan,and the latent soil nutrient benefit of unit area was 10.6×104 yuan·hm-2.Results of benefit subarea indicated the latent nutrient benefit was 12.2×104yuan· hm-2 in the east of Melmeg Reserve Wetlands,12.7×104 yuan· hm-2 in the middle and 7.6×104 yuan·hm-2 in the west.Contribution rate of the organic matter and kalium upon latent soil benefit was the biggest,and total phosphorus'was the least.Estimation on latent soil nutrient benefit makes up the weakness of wetland benefit assessment.The analysis of spatial distribution of benefit will provide theoretical basis for restoration and reconstruction of wetland.

Key words: wetlands, latent soil nutrient, benefit, spatial variation, Melmeg Natural Reserve
