Abstract
The process of rapid urbanization causes so many water security issues such as urban waterlogging, environmental water pollution, water shortages, etc. It is, therefore, necessary for us to integrate a variety of theories, methods, measures, and means to conduct ecological problem diagnosis, ecological function demand assessment, and ecological security pattern planning. Here, EC (Edge Computing) technology is applied to analyze the hydrological spatial structure characteristics and ecological planning method of waterfront green space. First, various information is collected and scientifically analyzed around the core element of ecological planning: water. Then, in-depth research is conducted on the previous hydrological spatial analysis methods to identify their defects. Subsequently, given these defects, the EC technology is introduced to design a bottom-up overall architecture of intelligent ecological planning gateway, which can be divided into field devices, EC intelligent planning gateway, transmission system, and cloud processing platform. Finally, the performance of the overall architecture of the intelligent ecological planning gateway is tested. The study aims to optimize the performance of the hydrological spatial analysis method and ecological planning method in Xianglan town of Jiamusi city. The results show that the system can detect the flood control safety system planning, analysis of water source pollution. Additionally, the system also can use the EC technology, depending on the types, hydrological characteristics, pollutants to predict treatment sludge need to put in the pollutant treatment medicament composition and dosage, protection of water source nearby residents public health security. Compared with previous hydrological spatial analysis and ecological planning methods, the system is more scientific, efficient, and expandable. The results provide a technical basis for the research in related fields.

The results show that the main pollutants in lake and reservoir water sources in China include chemical oxygen demand (COD), total nitrogen (TN), and total phosphorus (TP), and the pollution sources are mainly point source pollution, nonpoint source pollution, and internal source pollution

Summary
Water is essential for human existence, and human settlements are formed around water sources. Land areas surrounded by rivers, lakes, or oceans have become the best location for city construction because of convenient transportation and superior ecological environment. The 21st century has witnessed the emergence and popularization of ecological civilization [1,2], with which the traditional human-centered values are being replaced by the values of ecological civilization coordinating humans and nature. In terms of ecological civilization construction, the report of the 18th CPC (Communist Party of China) National Congress has pointed out the civilized ecological concept of respecting nature, conforming to nature, and protecting nature. Since the proposal of the concept of the ecological city in the 1970s, it has been developed and enriched in urban construction around the world [3]. Waterfront green space is an important part of the construction of an ecological city, whose development and
