Property rectification and greening

1. Main problems in greening of residential areas

(a) the green coverage rate is lower than the prescribed standard, or lower than the local average standard.

Green space coverage rate = (total land area-building area)/total land area.

According to China's national regulations, the reasonable green land in residential areas accounts for about 60% of the total residential area, and the green coverage rate cannot be lower than the standard of 30%. However, there are still many residential areas that fail to meet the prescribed standards, especially in the northern region, and the proportion of residential areas that can meet the prescribed standards is very small. The objective environment in the north leads to limited greening trees in residential areas in the north. The landscaping of greening plants is relatively monotonous and limited, and the maintenance and management costs are high and difficult, which affects the greening standard level of residential areas to some extent.

This study was conducted in Beibei, Chongqing, southwest of China, due to climate and other reasons. The residential area can basically meet the national requirements, but we should refer to the average green coverage rate in Beibei. Among them, the data of each cell is uneven. Some greatly exceed the average, such as Yunjing Hua Ting 42%; But there are also below average, such as 30.5% in Beiquan Garden. "When your home is surrounded by green trees, you are so cozy and comfortable." This is the heartfelt words of an owner interviewed in Yunjing Hua Ting.

See for yourself how I changed it for you. You ask too many questions and the key words are inaccurate. If you are in trouble, contact your tutor. It's your mentor, not us. You did it right, but it's no use if he said it wrong. Make a good change according to his meaning. Anyway, it seems to me that you have too many questions. As for your problem, it's not that you didn't major.
