线性工程切割耕地的权属调整方法及系统实现——以保阜高速顺平段沿线土地整治项目为例

论文以高速公路切割的耕地地块为研究对象,根据权属调整的不同方向,将权属调整分为所有权置换和使用权流转两种类型,并将权属调整的方法分为面积法和价值法;在GIS服务软件SuperMap iServer支持下,建立了一个交互式权属调整应用系统,以保阜高速顺平段沿线的高于铺镇、腰山镇土地整治项目区中的切割耕地为案例,应用系统生成了项目区高速公路沿线切割耕地的权属调整方案。研究结果表明,线性工程切割耕地需进行权属调整以保障农业生产,研究采用的权属调整方法符合当地实际情况,利用权属调整系统可以自动生成推荐权属调整方案,并可以根据用户需求进行调整,同时系统可以对权属调整相关数据进行动态管理。

Method and System Implement of Property Rights Readjustment of Cultivated Land Divided by Linear Project: A Case Study in Land Consolidation Project Along the Shunping Section of Baofu Highway

With the rapid urbanization and industrialization in China, linear network projects, including highway, railway, water conservancy, oil and gas pipe line, and other projects, develop rapidly. The construction and operation of linear projects lead to land fragmentation, destruction of water conservancy facilities, and problems of cultivated land quality. Because of the linear projects’ construction, the land along the linear projects is inevitably divided into two or more parts. Although the channel reservation and other measures can alleviate the problems, they bring difficulties to modernized agricultural production since large machines are not usable and daily farming activities are inconvenient in fragmented lands. Taking cultivated land divided by highway as a case, this paper explores the method of readjusting the property right of cultivated land divided by linear projects. In this case, the rights readjustment processes are divided into two types, replacement of ownerships and transfer of use rights, according to different readjustment policy. And two kinds of right readjustment methods, equal-area and equal-value, are proposed in this paper. The divided cultivated land plot must be readjusted form one side of the highway to the other side for the convenience of agricultural production. The replacement of ownerships is adopted if two villages readjust their lands each other, then the ownerships of the lands will be replaced and the way of compensation will be determined based on the land area or value. The transfer of use rights is adopted if the readjustment of land is single direction, then the land plot will be used by the other village and also the annual compensation will be determined based on land area or value. The equal-area method and equal-value method are suitable for different occasions. Equal-area method is easy, and it is applicable to lands with small difference in condition attribute difference is small; equal-value method is mainly applied to lands with different conditions, and it is not simply determined by the area conversion index. Supported by GIS service software—SuperMap iServer, an interactive web application for land rights readjustment is built. Taking the land consolidation regions of Gaoyupu town and Yaoshan town along the Shunping section of Baofu highway as the study area, and rights readjustment scheme of the cultivated lands divided by the highway is generated by the software system. The result shows that the generated schema is corresponding with the local situation. The software system can be used to generate rights readjustment scheme automatically, and the scheme can be modified according to user’s require-ments. In addition, the data used by the system can be managed dynamically.
