Importance of Water Ecological Environment Protection in Urban Landscape Design

Abstract

With the continuous acceleration of urbanization, urban construction has gradually become an important factor to promote the development of productive forces, the construction level of first-tier cities in China is higher than that of second-tier cities, and the economic volume is about several times that of other cities. Therefore, urban construction is an important factor to promote productivity. As a special regional type, a city watershed is a complex system with integrity and regionality. The particularity of urban watersheds lies in the fact that cities are characterized by the aggregation of elements. Cities are not only areas with densely populated population and buildings, but also the concentrated places of production, consumption and exchange. The development of cities is dynamic and diverse. The city ecological elements in the watershed are closely related, and the upstream and downstream regions are inseparable and affect each other. The current issues in the administration and conservation of the river basin’s water environment are due to conflicts of interest between the upstream and downstream of the city river basin, as well as between numerous departments. The conflict of interest and conflict of interests between the upstream and downstream of the urban watershed and various departments is the difficulty in the management and protection of the water environment in the current watershed. Water environment security means that there are clean and sufficient water resources to meet the needs of human survival, to meet the needs of social progress and economic development, and to maintain a good ecological environment. Water ecology refers to the influence of environmental water factors on organisms and the adaptation of organisms to various water conditions. Urban greening and landscape design are of great significance to the improvement of the ecological environment and the realization of sustainable urban development. This article takes the ecological landscape of a certain area as a research object to study the complexity, diversity, variability and other characteristics of modern ecological environmental problems, and analyzes the relevant situation of water pollution in the landscape ecological environment. The research shows that: permanganic acid in the water body around the lake The salt index, COD, BOD5, total phosphorus, and total nitrogen cannot meet the requirements of the Class III water environment functional zone. Among them, the highest pollution of the permanganate index is the W10 monitoring point, which exceeds 1.98 times, and the second is the W8 monitoring point, which exceeds 1.65 Times; COD pollution is the heaviest at the W7 monitoring point, exceeding the standard by 0.56 times; BOD5 pollution is the heaviest at the W8 monitoring point, exceeding the standard by 0.39 times; the heaviest total phosphorus pollution is the W11 monitoring point, exceeding the standard by 19.90 times. From the water quality testing data, it can be concluded that the water quality of the landscape area is seriously polluted, which seriously affects the drinking water safety of residents. In the process of modern urban garden landscape planning and design, only full use of ecological concepts can reduce the consumption of natural resources, avoid damage to the original ecological environment, and provide a more comfortable and healthy living environment for the people.
