我國(guó)建成區(qū)綠化覆蓋率與城鎮(zhèn)化率的關(guān)系研究
[Abstract]:The construction of urban green space is the key link of urbanization construction, and is affected by the process of urbanization. It is of great significance to reveal the internal relationship between urbanization level and urban green space construction level. This paper selects the green coverage rate of the built-up area and the urbanization rate of the population to represent the level of urban green space construction and urbanization respectively, and probes into the relationship between the greening coverage rate and the urbanization rate of the built-up area in China from two aspects of theoretical hypothesis and empirical test. The results show that: (1) there is an inverted "U" curve relationship between the greening coverage rate and the urbanization rate of the built-up area. That is to say, the promotion of urbanization rate on the growth of green coverage in built-up areas shows the basic law of gradually increasing to the peak at first and then decreasing gradually. (2) at present, the relationship between greening coverage and urbanization rate of built-up areas in China is in the middle of the relationship between greening coverage and urbanization rate. Reverse the left half of the "U" curve, The pulling strength increases with the improvement of urbanization rate. It is predicted that when the urbanization rate reaches about 65%, its impact on the greening coverage rate of the built-up area will reach the peak. After that, the pulling power tends to weaken. (3) due to the imbalance of urbanization level in each region, the urbanization rate also has significant differences in the intensity of improving the greening coverage rate of the built-up area, and the pulling strength is stronger in the middle and western regions. The pull force in the east is weak.
