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。Green space is a natural service system of the urban city,which plays an irreplaceable role in improving urban living environment and protecting the balance of urban ecosystem.In this study,an arid oasis city-Aksu was taken as an example,using the built area,population,urban greening coverage area,the per capita green coverage and rate of green coverage area in 1990—2014and analyzed the development trend of city size,population and land for 25 years,the city built-up area,population and greening coverage area deviation coefficient were estimated by coordinated modeling analysis,the population of built-up area,green coverage area,and growth rate of the coordinated development characteristics were laid out.The results showed that,from 1990 to 2014,the urban population decreased after increased twice,the built-up area and urban green coverage area continued to expand.The greening coverage rate and the per capita green cover area showed the corresponding improvement trend.The imbalance between built-up area and green coverage area growth rate was relatively imbalanced;coordinated development level between population and green coverage area was also low and severely imbalanced.Overall,the development of urbanization and greening in Aksu was in an uncoordinated state.Therefore,in order to realize the sustainable development of city and environment in Aksu city,the promoting the coordination of greening and urbanization should be a focus and the ecological benefits of urban green space should be given a priority.
