Water is called the “source of life”; it is the foundation of our human existence, and it is also an essential resource in the development of the country. Water pollution mainly includes two aspects. The first is that the water quality is polluted to a certain extent. Although our country has successively introduced many policies and measures to improve the water environment and reduce water pollution in recent years, people’s treatment of the water environment and the degree of attention is still not in place. The other is due to the extensive use of various pesticides and chemical fertilizers in the process of land planting and plant planting, resulting in a decrease in the water storage and drainage capacity of the soil. The quality of water resources has a certain degree of influence on the utilization efficiency of water resources. The full use of water resources refers to the use of water resources as raw materials or production costs into the production and operation process. While promoting urban development, the overall coordinated development of cities in adjacent or similar areas, especially cities with similar or the same water area, should be carried out, so that the development of each city and the development of the water area can coexist harmoniously. The theory of green development lies in the water. The definition in the efficient use of resources is to use the smallest possible investment in water resources in exchange for maximum benefits. This article organically combines the allocation of water resources with the protection and pollution control of the ecological and natural environment, so as to study the utilization of water resources in cities, and provide corresponding theoretical support for the improvement of the ecological environment of water resources and the increasing cleanliness.

水被称为“生命之源”；它是我们人类生存的基础，也是国家发展的重要资源。水污染主要包括两个方面。一是水质受到一定程度的污染。尽管近年来我国陆续出台了许多改善水环境、减少水污染的政策措施，但人们对水环境的治理和重视程度仍然不到位。另一个是由于土地种植和植物种植过程中大量使用各种农药和化肥，导致土壤的蓄水排水能力下降。水资源的质量对水资源的利用效率有一定的影响。水资源的充分利用是指以水资源为原料或生产成本投入生产经营过程。在推进城市发展的同时，要对相邻或相近地区的城市，特别是相近或相同水域的城市进行整体协调发展，使各城市的发展与水域的发展和谐共存。绿色发展的理论在于水。资源有效利用的定义是用尽可能小的水资源投资来换取最大的收益。本文将水资源配置与生态自然环境的保护和污染控制有机结合起来，研究城市水资源的利用，
