摘要: 本文以云南省丽江市拉市海高原湿地生态系统核心区为研究区域,利用区域生态系统功能监测指标和自然环境及人文活动因素指标,对拉市海高原湿地生态系统的健康状况进行空间综合评估分析。首先,根据当前生态系统的状况和高原湿地生态系统的特征,结合湿地保护区开展的系列生态系统功能监测项目及其指标,并充分考虑评估模型的系统性、科学性和实际操作的可行性,构建了拉市海高原湿地生态系统健康评价的指标和指标体系。然后,采用层次分析方法(AHP),融合自然综合指标、人文因素指标在内的生态系统健康综合评价模型,确定6级的生态系统健康评估标准;最后,根据空间评价模型和数据资源,对各个指标权重进行分析计算,得出拉市海高原湿地生态系统的健康状况的空间分布。研究结果表明,拉市海高原湿地的生态系统健康状况良好。按照划定的6级标准,其中,稳定区和较稳定区面积9 358.93hm2,占研究区域总面积的61%,脆弱区和较脆弱区面积为6 058.46hm2,占总面积的39%。整个研究区域内不存在很稳定区和极稳定区,这为高原湿地生态系统的综合管理及发展规划提供了依据。

Abstract: The objective of this research is to analysis wetland ecosystem health status of the core region of Lashihai Lake in Yunnan Province. Indictors that have impacts on ecosystem health were considered using the Analytic Hierarchy Process (AHP) methods. The integrated spatial analysis model was constructed to meet the requirements such as scientific research, systematicness and feasibility as well as data availability. Firstly, the indicators and indicator system were established based on the current status and characteristics of Lashihai Lake ecosystem, combined with series of items such as ecosystem functions monitor and indices under the principle of systematicness, scientificalness and feasibility. Secondly, using the AHP method, an integrated spatial analysis model for Lashihai ecosystem health study was constructed comprehensively and the 6-level assessment criterion has been established. Finally, the data-driven model run with existing data context and the weight of each indicators were calculated, and the spatial distribution of Lashihai Lake ecosystem health status were demonstrated by mapping.The research results show that ecosystem health in Lashihai Lake wetland is good, by there is no very stable and extreme stable region. The stable region is about 61% of the whole areas, and 39% of the areas is vulnerable area that should be paid more attention in future development. Especially, the eco-tourism developing activities across the lakeside region should be given scientific planning and proper management. The indicators and indicator system selected in this paper fit the true circumstances of Lashihai Lake region. The results can guide future planning in this region for both ecosystem management and economic development.
