浅析绿地率和绿化覆盖率的区别（Analysis of the difference between green space rate and green coverage rate） The rate of green space and the rate of green coverage are both economic and technical indexes to measure the greening condition of residential areas. The rate of green space is not equal to the rate of green coverage. The green space rate is the ratio of the sum of all kinds of green spaces in the residential area and the proportion of the land in the residential area (%). The basic formula of green coverage rate is the same as the formula of green space rate in the form. But the specific technical indicators are not the same. (1) the rate of green space: strict control and high standard; When calculating the rate of green land, the requirement of green space is very strict. Green space rate refers to all kinds of green land within the residential area, mainly including public green space and green space beside the house. Among them, the public green space, including residential areas, parks, small garden, green and other groups of groups of public green belt. Even the lowest level of scattered massive, public green strip also requires a width of not less than 8 meters, an area of not less than 400 square meters, the land within the green area of not less than 70% of the total area (including water), at least 1/3 of the green area to be perennial under direct sunshine, and to add part of leisure and entertainment facilities. And the residential green space, such as green land, in the design and calculation, but also requires 1.5 meters from the outer walls of buildings and roads within 1 meters of land, shall not be included in the green land. In addition, there are several situations in the green rate of greening area, underground garage, underground buildings covering the top surface of the high relative design of outdoor floor elevation is less than 1 meters, the average soil thickness not less than 1 meters, Joe, shrub planting area ratio should not be less than 70% of t
