【摘要】：永久基本农田划定是当前国土资源管理一项十分重要而紧迫的任务,其对维护粮食安全和控制城镇无序增长具有重要意义。永久基本农田划定不仅要满足耕地质量较高而且还要集中连片,更需要协调城镇化矛盾。因此,如何从土地利用现状数据库中提取永久基本农田保护图斑实际上是一个复杂的空间数据挖掘过程。研究利用农用地分等成果定义保护片区质量,利用元胞自动机模拟分析土地利用矛盾,利用种子扩充算法进行保护片区搜索,利用神经网络进行耕地保护压力预警。基于C#和Arc Engine10.1将多种空间数据挖掘模型进行集成,构成了面向全域永久基本农田识别的智能系统工具包iZone,并在广东省高要区金利镇进行实例应用。研究表明,iZone能按既定规则从土地利用现状数据库中提取保护图斑,有效避免了人为划定的过多主观性,并且能获得与人工方案相当乃至更好的表现。iZone利用复杂地理计算技术进行永久基本农田智能识别,可提高永久基本农田划定工作的科学性。
[Abstract]:The delineation of permanent basic farmland is a very important and urgent task in the management of land and resources at present. It is of great significance to maintain food security and control the disorderly growth of cities and towns. The definition of permanent basic farmland should not only satisfy the higher quality of cultivated land, but also focus on the continuous development, and coordinate the contradiction between urbanization and urbanization. How to extract the map of permanent basic farmland protection from the database of land use status is actually a complicated process of spatial data mining. Using cellular automata to simulate and analyze land use contradiction, seed expansion algorithm is used to search protected area, neural network is used to predict cultivated land protection pressure, and several spatial data mining models are integrated based on C # and Arc Engine10.1. The intelligent system tool kit iZonefor the identification of the whole area permanent basic farmland is constructed and applied in Jinli Town, Gaodao District, Guangdong Province. The research shows that the Zone can extract the protection map spots from the database of land use status according to the established rules. It can effectively avoid the excessive subjectivity of artificial demarcation, and can obtain the performance. IZone, which is comparable to or even better than the artificial scheme, can use complex geographic computing technology to identify permanent basic farmland intelligently, which can improve the scientific nature of permanent basic farmland demarcation.
