【摘要】：绿地是城市的自然服务系统,对改善居民生活环境、保护城市生态系统平衡起着不可取代的作用。该研究以干旱区绿洲城市—阿克苏市为研究对象,采用1990—2014年的建成区面积、人口、城市绿化覆盖面积、绿化覆盖率、人均绿化覆盖面积等统计数据,分析25年来城市规模、人口与绿地的发展变化趋势,并通过协调性分析模型估算本市建成区面积、人口与绿化覆盖面积的离差系数,揭示了人口-建成区面积-绿化覆盖面积增长率协调发展特征。结果表明:1990—2014年间,城市人口出现2次先增加后下降态势,建成区面积与城市绿化覆盖面积不断扩大。绿化覆盖率与人均绿化覆盖面积变化呈现出相应的改善趋势。建成区面积与绿化覆盖面积增长率失调比较严重,且失调等级为重度失调;人口与绿化覆盖面积协调发展水平也偏低,失调等级为重度失调。总体来看,阿克苏市城市化与绿地协调发展水平处于不协调状态。因此,为实现阿克苏市城市发展与生态环境的可持续,应着力促进绿化与城市化相协调,优先考虑并提高城市绿地的生态效益。
[Abstract]:Green space is the natural service system of the city, which plays an irreplaceable role in improving the living environment of residents and protecting the balance of urban ecosystem. Population, urban greening coverage, greening coverage, per capita greening coverage and other statistical data are analyzed, and the development trends of urban scale, population and green space in the past 25 years are analyzed, and the area of established areas of the city is estimated by the coordination analysis model. The coefficient of deviation between population and greening area reveals the characteristics of coordinated development between population, built-up area and green coverage area. The results show that the urban population increased first twice and then decreased between 1990 and 2014. The area of the built-up area and the area covered by the urban greening are expanding continuously. The change of the greening coverage rate and the per capita greening coverage area shows a corresponding improvement trend. The growth rate of the built-up area and the greening coverage area is quite serious. And the level of imbalance is serious, and the level of coordinated development of population and greening area is also low, and the level of imbalance is serious. In general, the level of coordinated development of urbanization and green space in Aksu is in an uncoordinated state. In order to realize the sustainable development of urban and ecological environment in Aksu City, it is necessary to promote the coordination of urban greening and urbanization, and to give priority to and improve the ecological benefits of urban green space.
