When the reporter visited many green parks and camping camps in Beijing and Chengdu, he saw that some flat grasslands and beaches were "long" covered with all kinds of tents. Portable tables and chairs were standard. The tables were filled with all kinds of food, drinks and drinks, and some had barbecue racks and cooking utensils. "Camping has entered a popular era. It seems that in an instant, every piece of grass is full of campers." An industry source said. Chengdu citizens have purchased camping equipment since the beginning of next year. Every weekend, they will ask several families to form a team to go camping outdoors. "From the beginning, we simply set up a chair and a small table to drink tea. Later, we set up a tent and cook with cooking utensils. Now we live outdoors for one night. The way of camping is changing, and more and more equipment are purchased." Bao Ming said. The reporter's investigation found that in the past two years, the epidemic prevention and control has been normalized. Many cities call for "not leaving the city unless necessary", and more and more people choose camping. Many campers said that in the process of camping, they can better experience the feeling of being close to nature and having fun with relatives and friends. However, behind the exquisite and beautiful camping photos of the circle of friends and high-end atmosphere, some problems deserve attention. Many professional camping enthusiasts said that the biggest impact of suddenly blooming camping is environmental damage and prominent pollution problems. In wanghonglu camp, haiwozi ancient town, Pengzhou City, Chengdu, the reporter saw that when the Jianjiang River flows through here, the river channel narrows, the river beach is gently exposed, and the surrounding vegetation is dense. According to local villagers, every weekend or holiday, the beach will be crowded with a tent. When tourists disperse at the end of the holiday, they will always leave a lot of garbage. Even campers pour all kinds of waste water and residues directly into the river. In addition to professional campsites, most people choose areas close to water, flat grassland and lush vegetation for camping. The reporter's investigation found that in some urban parks, some vegetation was seriously damaged, camping produced a lot of garbage, and some directly polluted the water area. In addition, the safety risks brought by camping deserve vigilance. Many campers like to use open fire, barbecue and even cook, which has great potential safety hazards. In some parks and riverbanks in the urban and suburban areas of Beijing, many campers set up barbecue racks and kebabs. There was smoke and fire on the scene, and sparks came out from time to time. In Huaixin park on the South Fourth Ring Road, the reporter saw tourists barbecue in the woods, and a lot of poplar catkins were accumulated on the ground under the woods. Once the fire is not used properly, it is very easy to have a fire. The reporter saw in a professional campsite in Huairou District of Beijing that the camp has specially opened up a self-help barbecue area, with special staff to light charcoal fire and prepare food materials to ensure the safety of fire. "The outdoor environmental protection concept of 'traceless camping' has not been popularized. This concept requires people participating in camping to plan and prepare in advance, camp on tolerable ground, properly dispose of garbage, maintain the natural appearance as far as possible, reduce the impact of outdoor fire on the environment, pack food residues and take them away, and reduce the use of soap cleaners." Shen Wei, a senior outdoor adventure enthusiast in Chengdu, said. Song Yu, an assistant researcher at the Institute of Sociology of the Chinese Academy of Social Sciences, said that camping meets people's leisure needs, but the next step should be standardized to guide the healthy and orderly development of the industry. Deal with and rectify the operating campsites without qualification, strengthen the standardization of camp design and operation, and strengthen the supervision of acts such as damage and pollution to the environment.
