河道治理是通过工程与非工程措施对河流进行系统性修复与管理的活动,旨在平衡防洪、生态、景观等多重功能需求。
一、治理原则与目标
.综合性原则:统筹防洪排涝、生态修复、景观协调等功能,确保河道满足人类需求与自然平衡。
.自然性原则:优先采用生态工法(如透水材料、本土植被),减少人工干预,恢复河道自净能力。
.经济性原则:优化成本效益,兼顾建设与后期管护的可持续性。
二、主要治理措施
1空间管控
划定河道管理范围,明确岸线保护区(如长江、黄河岸线保护率达70%)。
清理“四乱”(乱占、乱采、乱堆、乱建),拆除违建1.5亿平方米,恢复水域面积1300平方公里。
2生态修复技术
硬质护岸改造:替换为生态护坡,构建生物栖息环境。
湿地构建:人工湿地日处理水量达130万吨,如茅洲河治理后水质提升至Ⅳ类。
3智慧化管理
应用卫星遥感、AI识别等技术,实现全国30万条河湖基础数据动态监测。
River management is the activity of systematically restoring and managing rivers through engineering and non engineering measures, aiming to balance multiple functional needs such as flood control, ecology, and landscape.
一、 Governance principles and objectives
The principle of comprehensiveness: coordinate functions such as flood control and drainage, ecological restoration, and landscape coordination to ensure that the river meets human needs and balances with nature.
Principle of naturalness: Prioritize the use of ecological construction methods (such as permeable materials and local vegetation), reduce human intervention, and restore the self purification capacity of the river channel.
Economic principle: Optimize cost-effectiveness and balance the sustainability of construction and later management.
二、 Main governance measures
1. Space control
Define the scope of river management and clarify the shoreline protection areas (such as the protection rate of the Yangtze River and Yellow River shorelines reaching 70%).
Clean up the "four chaos" (illegal occupation, illegal mining, illegal stacking, and illegal construction), demolish 150 million square meters of illegal buildings, and restore 1300 square kilometers of water area.
2 Ecological Restoration Technologies
Hard revetment renovation: Replace with ecological slope protection and build a biological habitat environment.
Wetland construction: The daily processing capacity of artificial wetlands reaches 1.3 million tons, and the water quality of Maozhou River has been improved to Class IV after treatment.
3. Intelligent management
Using satellite remote sensing, AI recognition and other technologies, achieve dynamic monitoring of basic data of 300000 rivers and lakes nationwide.
