江阴市率先设立“不开发区”的做法,已在全国范围内引起广泛关注,可称作是中国版“精明增长”的典范。具体方法是:首先采用SPOT和TM卫星遥感融合影像和人工解译方法,提取生成具有较高精度的区域土地利用现状图;然后根据不开发适宜性与灾害、农业、生态、建成区等地理因子分布的关系,采用缓冲区分析、叠加分析等GIS手段,制作形成区域不开发适宜性综合评价图;之后,基于区域土地利用现状图和不开发适宜性综合评价图,运用生态安全网络原理,借鉴自然保护区管理经验,科学划定不开发区及其核心区的位置和范围;最后,对于划定的不开发区,规划提出只允许发展现代农业和生态旅游业,限制开展大工业开发和高强度城镇建设活动,并将现有工业企业逐步转移至工业园区的保护措施。这种地方政府主动划出一定土地留给未来开发的良好实践,比单纯地城市扩张战略更先进,对促进我国苏南发达地区土地利用布局优化具有十分重要的意义。
Jiangyin City, the first to set up a “non-development zone” approach, has aroused widespread concern throughout the country, can be called the Chinese version of “smart growth” model. The specific methods are as follows: First, SPOT and TM satellite remote sensing fusion images and artificial interpretation methods are used to generate the map of land use status with high precision; then according to the geographical factors such as suitability and disaster, agriculture, ecology, built-up area Distribution, the use of buffer analysis, overlay analysis and other GIS means to create a comprehensive assessment of the region to develop a comprehensive evaluation; then based on the regional land use map and the comprehensive evaluation of suitability development map, the use of ecological safety network principles, learn from Finally, regarding the designated undeveloped areas, the plan proposes that only allow the development of modern agriculture and eco-tourism, limit the development of large-scale industries and the development of large-scale industries Intensify the urban construction activities, and gradually transfer the existing industrial enterprises to industrial parks. Such local governments take the initiative to draw aside certain land for good practice in future development, which is more advanced than simply urban expansion strategy and is of great significance to the optimization of land use layout in developed areas of southern Jiangsu.
