The first one is mainly to strengthen the supervision of environmental protection and environmental supervision. Of course, we are also very happy. Now the city is going to organize a public security law enforcement team soon. The second aspect is to strengthen the management of cargo transportation, especially in some areas near Hangzhou, where ships with dangerous goods are not allowed to enter. Of course, we should also improve the coordination ability, and the third is to build an early warning system for water quality. Because our 40-odd surveys are basically not predictable, I think there should be so many high-tech means now, and this means of establishing water quality monitoring information through various Internet means can be found in time. Fourth, there should be backup measures to build Xianlin Reservoir as soon as possible.

The first suggestion is to establish a higher-level coordination organization in Hangzhou as far as possible, which can really contact various departments and cross-departments, such as its responsibilities and interests, and can really achieve coordination. More measures should be taken to research and explore some water sources, and it should also be mentioned that the construction of standby drinking water source system should be accelerated. Why do we call it a system? Because we don't just say that Tiesha River or so-and-so River is our backup water source, in fact, these water bodies are all connected. Once the Qiantang River is polluted, the whole Tiesha River and other rivers will also be polluted.

Therefore, we establish standby drinking water sources, including reservoir drinking water sources and groundwater drinking water sources. I think what they said is very reasonable in many aspects. First of all, I want to talk about the characteristics of the Qiantang River system. Qiantang River is 668 kilometers from its birthplace, Xiuning County, Anhui Province, to our estuary. Our river basin covers an area of 56,000 square kilometers, including 48,000 square kilometers in Zhejiang Province. This route passes through Quzhou, Jinhua and Lishui, which is our upstream. I won't talk about the downstream. There are three main streams in the upper reaches and tributaries in the basin. There are 8 tributaries with an area of 1000 square kilometers or more. There are 143 watersheds and pumping areas, with an area exceeding 100 square kilometers. In Qiantang River Basin, there are about180,000 people living, and the industry in this basin is relatively developed. By the way, I also want to talk about the water system of Qiantang River, which is not only an ecological function of our tap water, but also a polluted water body. There are so many rivers in the upper reaches of our country that all sewage treatment plants, including our domestic sewage and industrial sewage, will eventually enter Qiantang River. The main city of Hangzhou is just downstream of our Qiantang River, which means that the water quality of our Qiantang River is largely controlled by the upstream. Two-thirds of the time is spent in Ganxi Lake, which means that our water source is mainly coupled with our own environmental protection. At the same time, it is more important that we strengthen the management of environmental protection in the upstream.
