国家自然保护区湿地边界划分与质量评价研究——以扎龙国家级自然保护区为例

Boundary Definition and Quality Evaluation of Wetland in National Nature Reserve——Take Zhalong National Nature Reserve as an Example

本文以扎龙国家级自然保护区湿地为研究对象,采用抽样土地调查和遥感调查技术相结合的方法,建立扎龙国家自然保护区的湿地质量评价指标体系。经过调查评估发现,扎龙国家级自然保护区湿地水资源相对稀缺,自然降雨无法维持湿地的生存,水资源得分为65分;土壤状况良好,土壤质量得分为80分;土壤有机质含量较高,得分为100分;湿地破碎化程度相对较重,景观格局指数得分最低,为49分。对扎龙国家级自然保护区湿地状况的分析可以为未来其他保护区的分析提供一些思路和线索。

This article takes the wetlands in Zhalong National Nature Reserve as the research object.A method combining sampling land survey and remote sensing survey technology to establish an evaluation index system of wetland quality for Zhalong National Nature Reserve was adopted.The result showed that the water resources of Zhalong National Nature Reserve wetland are relatively scarce,and natural rainfall cannot maintain the survival of the wetland.The water resource score is 65 points;the soil condition is good,and the soil quality score is 80 points.The organic matter content of soil is relatively high,with a score of 100 points;the wetland fragmentation degree is relatively heavy,and the landscape pattern index score is the lowest,with a score of 49 points.The analysis of the wetland status of Zhalong National Nature Reserve can provide some ideas and clues for the analysis of other protected areas in the future.
