摘要

摘要:
以粤北山区翁源县为例，综合水资源、水灾害与水环境视角，结合县域地形、水文、生态保护、国土现状调查、实测水质采样等数据及相关规划、标准，运用水源欧氏缓冲结合涵养量计算、蓝点模型模拟和水环境载荷量计算方法，分别对区域水资源、水灾害与水环境安全格局进行计算与分析，并在此基础上构建区域多视角下的综合水安全格局。结果显示：翁源县水资源、水灾害和水环境安全格局分别与重要水系和相关保护区及地形地貌，滃江水系上、中、下游位置及周边人类活动强烈程度，水体污染状况密切相关。翁源县综合水安全格局中的低安全区主要分布于饮用水源、自然保护区、重要水系廊道与水源涵养区及周边毗邻区等生态敏感脆弱区；中安全区主要分布于低安全生态敏感脆弱区的缓冲区，及其毗邻影响区域；高安全区主要分布于中安全缓冲区外围区域及其毗邻影响区。翁源县综合水安全格局中较敏感脆弱的低和较低安全区，与建设用地和永久基本农田保护区存在较小面积冲突管控区，而与生态保护红线和水土保持治理空间保持较高的契合度，表明研究结果与用地管控、相关保护规划和治理空间具有较好的一致性。

Abstract:
Taking Wengyuan County in the mountainous area of northern Guangdong Province as an example, the authoritative research data sources in the fields of water resources, water hazards and water environment were adopted, combined with data on county topography, hydrology, ecological protection, land status survey, measured water quality sampling, etc., as well as related planning and standards. By using the methods of Euclidean distance buffer for water source combined with conservation capacity calculation, Bluespot model simulation and water environment load calculation, the regional water resources, water hazard and water environment security pattern were calculated and analyzed. On this basis, a comprehensive water security pattern under regional multi-perspectives was constructed. The analysis results showed that the security patterns of water resources, water hazards and water environment in Wengyuan County were closely related to the important water systems and related protected areas and landforms, the location of the upper, middle and lower reaches of Wengjiang River system and the surrounding intensity of human activities, and the pollution status of the water bodies, respectively. The low security areas in the comprehensive water security pattern of Wengyuan County were mainly distributed in ecologically sensitive and fragile areas such as drinking water sources, nature reserves, important water system corridors and water conservation areas and surrounding areas; the medium security areas were mainly distributed in the buffer zone of the low security ecologically sensitive and fragile area, including the adjacent affected area; the high security areas were mainly distributed in the periphery of the medium security buffer zone and its adjacent affected areas. In the comprehensive water security pattern of Wengyuan County, there was a small area conflict control area between the sensitive and fragile low security area and the construction land and permanent basic farmland protection area. However, it had a high degree of agreement with the redline of ecological conservation and the management space of soil and water conservation, which showed that the research results were in good agreement with the space of land management, related protection planning and practical management.
