The population has soared and the land has plummeted-a serious worry in contemporary Jimo; Developing water resources and protecting the environment-a long-term plan to improve the government and benefit the people. Before 2000, the most prominent doctor in Jimo was just a "doctor of ten thousand people", and each "family" counted five people. At that time, there were only fifty thousand people, and there were even more rare times. /kloc-at the end of June, there were less than 30,000 people in each county, and the county area at that time was more than 900 square kilometers larger than today. In other words, there were hardly 10 people per square kilometer at that time. This is really amazing compared with today's population phenomenon. The population of Jimo increased continuously in modern times. 1872 has a population of 370,000, and 196 1 year reaches 770,000. In other words, it decreased by 1 1 000 in three years, which was considered as a small return in the population tide and then surged. 1969, with a population of 800,000; 1975 reached a new level of 900,000 yuan; 1 10,000 mark was broken under great control in 1987, and the population density correspondingly reached 562 people/km2. Obviously, the speed of population growth is getting faster and faster, which is worrying; How many people's land is Jimo most suitable for? Less than 30,000, more than 6,543.8+0,000. As worrying as population expansion is the decrease of land. When there are only 65,438+00 people per square kilometer, it is surprising that people do not have enough to eat and wear. Now more than 560 people can eat and wear warm clothes on a square kilometer of land. The only thing we are proud of is the superiority of the socialist system in the new era, and nothing else. We can't help but be soberly aware that the contradiction between "more people and less land" is getting worse. In the history of Jimo County, more than 2.7 million mu of land has been developed, and 370,000 people have been fed, with a per capita occupation of more than 7 mu. This was more than 65,438+000 years ago. With the increase of population and the continuous expansion of various social constructions, nearly 10,000 mu of cultivated land has been occupied by various constructions every year since 1950s, that is to say, hundreds of thousands of mu of land have disappeared today. If we develop at this tense speed, how will we stand after 65,438+000 years? Don't be careless Now we rely on 1 more than ten thousand mu of cultivated land to feed 1 more than ten thousand people, and the population continues to grow. It can be said that the land can only be reduced and it is difficult to expand. What should I do in the future? Although we rely on gradually improved modern farming techniques to continuously increase food production without worrying about eating, it is limited. Nowadays, the per capita arable land in Jimo is less than 1.36 mu, while the population continues to grow, the construction continues to expand and the arable land continues to decrease, which is an increasingly serious problem facing Jimo County.

Historically, Jimo did not seem to be a place short of water. During the Ming and Qing Dynasties, over the past 500 years, Jimo suffered 32 floods and 1 1 droughts. Obviously, there are more floods than droughts. According to the observation data for 20 years since 1950s, the average annual natural precipitation is about 750mm. However, in recent years, the drought has continued and the drought is very serious. Water is in short supply, and the groundwater level drops. There are few rivers, bays and ditches in the county, and even residents have no drinking water. The reason is not only lack of rain and drought, but also poor water control. Jimo is located near the sea, and rivers are generally fast-flowing, which is easy to discharge and difficult to collect. According to the 1980 water resources survey, our water resources utilization rate is only 2 1.7%, and the water resources utilization rate of transit rivers is only 9%, which means that God gives us 10 barrels of water every year, and we only use one or two barrels, and the other eight or nine barrels are wasted. Macroscopically, 32: 1 1 or 750 mm, water seems to be enough in Jimo; However, due to the excessive concentration of precipitation, the trench is often filled within a few days or a heavy rain, and the land is close to the sea, and the rainwater is over-utilized. Therefore, Jimo's water control lies in water storage, water storage and drought regulation, so as to achieve a balance between drought and flood. "Those who want to flow far away will dig their springs." Where there is water, fish are born, and Maki Ka is prosperous; Without water, crops wither and forests wither. Water is the source of "enriching the people and rejuvenating the country", so we should take a long-term view.

Environmental problems are also a new subject that needs urgent consideration before the people of Jimo. The natural environment is getting worse and worse, and the ecological balance is becoming more and more inclined. With the rapid development of modern industry, enterprises compete, such as dragon boat racing; Mantis catches cicada, yellowbird is behind, and all kinds of pollution take the opportunity to attack. Take the Mohe River in jimo city as an example. Historically, it is picturesque and elegant. Take the old theory as evidence: a scene called "Smooth Sand and Clear Flow": the broad river surface is rippling, and the flat river bottom is clean with fine sand; The second scene is called "Lock Longquan Stone": the river suddenly turns to the ravine, turbulent and ups and downs; The waves splashed and the water buzzed. The third scene is called "Fishing on the High Embankment": the riverbank suddenly rises, the trees on both sides are lush, and the silver scales leap over the blue waves on the fishing embankment. Its scenery is called "Huai is involved in spring": dragging willow, morning mist cage yarn, running water, and clothes are broken. Now all this has disappeared without a trace, replaced by sewage gurgling, making people cover their noses. Water pollution, air pollution and land pollution are coming from all directions, surrounding the life of modern Jimo residents. Contemporary people should think of future generations and make comprehensive and systematic plans for long-term stability. It is gratifying that people pay more and more attention to the problems of population, land, water and environment, and the county party Committee and government are actively implementing various measures and have achieved results.
