基于细河流域生态健康评价
|
摘要
以细河流域为例,在遵循可获取性、科学性、代表性、系统性原则的基础上选择3项典型指标并建立评价体系,然后运用综合指数法科学评价了流域生态健康状况。结果显示:细河流域陆域生态格局与水生生物状况相对较差,流域生态健康总体呈现出良好的状态;流域内影响生态健康退化的主要因素有不合理的岸边带种植、畜禽养殖等,为改善流域健康状况建议加强对涉水活动干扰水生生境的监管和污染负荷排放的控制,从而实现流域的适应性与可持续性管理以及河流水系的生态安全。
Taking the Xihe River Basin as an example, three typical indicators are selected and an evaluation system is established on the basis of the principles of accessibility, scientificity,representativeness and systematicness, and then the ecological health status of the basin is scientifically evaluated with the comprehensive index method. The results show that the land ecological pattern and aquatic organisms in the Xihe River Basin are relatively poor, and the ecological health of the river basin is generally in good condition. The main factors affecting the ecological health degradation in the river basin are unreasonable coastal planting, livestock and poultry breeding, etc. In order to improve the health of the river basin, it is suggested to strengthen the supervision of the disturbance of water-related activities on aquatic habitats and the control of pollution load discharge. The adaptability and sustainable management of the river basin and the ecological security of the river system are realized.
