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 was the earliest to conduct Non-development zone planning and has attracted the attention of people al over China because it is regarded as the Chinese version of Smart Growth. The planning process is as folows. Based on SPOT and TM satelite remote sensing images develop a regional land use map with high preci-sion using artificial interpretation methods. Then, according to the relationship between anti-development suitability and disasters, agriculture, ecology, built-up area distribution and other geographical factors, generate a compre-hensive evaluation chart of anti-development suitability using GIS analysis, such as buffer analysis and overlay analysis. Later, with a regional land use map and anti-development suitability evaluation chart, using the principle of ecological security network and learning from the management experience of nature reserves, draw the scope of Non-development zone and core area. Last, put forward a series of protective measures for the above Non-development zone, that is only allowed to develop agriculture and tourism, strictly restricted industrial projects and urban real estate activities, and al existing industrial factories must be moved to planned industrial parks. This is good practice whereby local governments keep land resources for future generations and more advanced than an urban expansion strategy. This method is very useful for promoting land use layout optimization in Southern Ji-angsu Developed Areas.
