利用2000、2005、2010年航空遥感影像解译的崇明岛土地利用数据,结合同期社会经济数据,研究政策驱动下的崇明岛城市生态空间变化规律。研究表明:2000~2010年,崇明岛生态空间快速增加,后五年较前五年增长幅度更大;除东滩地区外,其余乡镇的生态空间均有增长,后五年的变化幅度较前五年大;崇明岛生态空间格局趋于稳定,后五年的好转趋势优于前五年。崇明生态岛建设政策驱动下的绿色景观规划和管理是岛屿生态空间提升的主要因素,同时,由于政策的驱动,生态胁迫对崇明岛生态环境的影响也有所减弱,可以看出,政府的干预和调控行为对生态空间的管理和保护具有极其重要作用。
Based on the data of land use of Chongming Island interpreted by aerial remote sensing images from 2000, 2005 and 2010, and combining with the socio-economic data of the same period, we study the urban ecological spatial variation of Chongming Island driven by the policy. The results show that from 2000 to 2010, the ecological space of Chongming Island increased rapidly, and the growth rate of Chongming Island increased more in the next five years than that of the previous five years. Except for Dongtan area, the ecological space of the remaining towns and townships increased with the increase of the past five years Five-year-old. The ecological spatial pattern of Chongming Island tended to be stable. The improvement trend of the past five years was superior to the previous five years. The planning and management of green landscapes driven by the construction of Chongming Ecological Island is a major factor in enhancing the ecological environment of the island. At the same time, the impact of ecological stress on the ecological environment of Chongming Island also weakened due to the policy drive. It can be seen that the government intervention and Regulatory behavior plays an extremely important role in the management and protection of ecological space.
