Electronic map of MapInfo is introduced into the environment of object oriented by the use of Map X 4.0 module. The operations such as dynamic add, delete and edit of objects can be done real-time dynamically by operators in the environment of object oriented on the present diagram of polder region. At the same time, the spatial-data and attribute-data of irrigation district are managed separately. The spatial-data is used by the file system, whereas, the attribute-data exist in the relevent database. The figures and database are related through the only ID number in order to realize two-way inquiry, so that, the polder region river system planning data are collected automatically. Moreover, this system make the great use of GIS advantage in storing and annalising data to automatically organize files needed in river network calculation , adopt one-dimensional unsteady flow model , so as to lay out height of river levee .

把GIS技术引入水系规划，通过MapX4.0组件把MapInfo电子地图调入面向对象编程环境，使操作人员能在面向对象环境中对圩区现状图进行实时动态操作，包括对操作对象的动态添加、动态删除、编辑等；同时，将空间数据和属性数据分开进行管理，空间数据用文件系统管理，属性数据采用数据库管理，通过建立唯一ID号进行数据联接，将图形与数据库进行关联，实现属性到图形或图形到属性的双向查询，从而实现了圩区水系规划部分数据的自动采集；另外，本系统充分利用GIS存储与分析数据的功能，自动生成河网水力计算所需的文件，采用一维非恒定流模型进行河网水力计算，为确定沟道堤顶高程提供依据。

Firstly, affine covariant neighborhoods of visual words are used to verify the spatial consistency. Secondly, a set of affine transformation matrices between the corresponding covariant regions is calculated, and the matrix with the most inliers is chosen as the best matching affine transformation matrix. In this step, only a single pair of corresponding affine covariant regions is used to calculate the 6 degree of freedom affine transformation for acceleration. In the last step, the spatial consistency is verified by the BMATM.

首先通过视觉关键词仿射协变的空间邻近特征集进行初步空间关系一致性匹配；然后计算对应仿射协变区块的多组可能的仿射变换矩阵，并选择满足区块匹配最多的变换矩阵作为对象与图像之间最终仿射变换矩阵，其中，仅利用一对协变区块来计算自由度为6的仿射变换的算法有效地提高了计算速度和鲁棒性；最后通过计算出的仿射变换矩阵来精确验证对象与图像之间的空间位置关系是否一致。

A geostatistical method was put forward to analyse the spatial variability of combined heavy metal pollution in soils based on GIS. The spatial analysis showed a combined Cu and Cd pollution occurred in the research area, Cu was mainly concentrated in surface layer, but Cd had high concentrations in 0-60cm depth of soil profile. The correlation analysis revealed that the point source pollution was dominated by the pollution let-out of the smeltery.
