Problems solved by technology

[0005] In order to solve the problems of water quality deterioration and ecosystem degradation of shallow artificial lakes in parks, the present invention provides a systematic ecological restoration method for shallow artificial lakes, which can effectively reduce external non-point source pollution of artificial lakes, improve the self-purification ability of water bodies, and restore biodiversity. Enhance the stability of the ecosystem function and improve the ecological landscape effect of the lake area; at the same time, it can avoid the impact on the external environment and reduce the project cost

Embodiment Construction

[0026] As shown in the figure, a systematic shallow water artificial lake ecological restoration method provided by the present invention includes the following technical contents: 1) treatment and disposal of shallow water artificial lake sediment; 2) underwater forest construction 102; 3) bank slope ecological restoration 103; 4) Plant gate construction 104 at the entrance to the lake; 5) Reoxygenation 105; 6) Biological manipulation 106.

[0027] Detect water pollution indicators and sediment pollution indicators of shallow artificial lakes before restoration; the water pollution indicators include pH, conductivity, turbidity, chemical oxygen demand, ammonia nitrogen, total phosphorus, permanganate index and chlorophyll , sediment pollution indicators include organic matter and mercury.

[0028] The treatment and disposal of the bottom mud of the shallow water artificial lake refers to selecting a silted or basically silted bay end of the artificial lake and transforming it...

Abstract

The invention provides a systematic shallow water artificial lake ecological restoration method. The method comprises the following steps: 1) shallow water artificial lake sediment treatment and disposal; 2) underwater forest construction; 3) bank slope ecological restoration; 4) lake inlet plant bar construction; 5) reoxygenation aeration; and 6) biomanipulation. The method can effectively the external non-point source pollution of the artificial lake, improve the self-purification capacity of water, recover the biological diversity, enhance the functional stability of an ecological system and improve the ecological landscape effect of a lake area, and also can avoid the influence on the external environment and reduce the engineering cost.

Description

technical field [0001] The invention relates to a systematic shallow water artificial lake ecological restoration method. Background technique [0002] With the development of social economy and the improvement of living environment, people are increasingly aware of the important role of the water system in the park in regulating the microclimate, beautifying the landscape, and protecting biodiversity. For this reason, the builders increasingly regard the construction of the park landscape water system as a highlight in the construction of public activity parks, campuses, office parks, and residential parks, and there are more and more related cases. [0003] However, due to the lack of research on ecological construction technology and water pollution control technology by the builders, there are often problems such as water quality deterioration and ecosystem degradation in domestic park water systems, and the ecological landscape effect is greatly reduced. Especially the...
