| 摘 要： | 解决耕地占补平衡中补充耕地数量和质量不到位等问题,对保障国家的粮食安全具有重要意义。该文借助GIS的空间分析功能,以鄂尔多斯-安平-沧州输气管道工程(盂县段)项目为基础,进行微观案例分析,探索农用地分等及土地开发整理成果在耕地占补平衡中的具体应用。研究结果表明:1)基于农用地分等成果,可以准确定位被占耕地的数量及空间布局,经过计算和分析,确定被占耕地等级。2)基于农用地分等和土地开发整理成果,可以确定补充为耕地的土地利用等别、数量及空间布局,补划为基本农田的一般农田的等别、数量及空间布局;可以保证补充耕地的等级和数量不低于被占耕地的等级和数量;补划为基本农田的等级和数量不低于被占基本农田的等级和数量;补充的耕地与其他耕地集中连片。3)耕地异地占补平衡当中,交易机制不健全,耕地占补平衡指标价格区域间差异甚大,在解决耕地占补平衡指标交易问题的基础上,将补充耕地及基本农田补划的方法推广到耕地异地占补平衡中,为耕地占补平衡提供更科学的方法。

| Abstract: | To improve the poor quantity and quality of the supplementary cultivated land, cultivated land requisition- compensation balance is of great significance for national food security. The paper discusses the application of results of agricultural land gradation and land consolidation to the cultivated land requisition-compensation balance with GIS spatial analysis function, which was based on case analysis of the Ordos - Anping - Cangzhou Gas Pipeline Project (Yuxian Section). After stack process of maps of overall land use planning in towns and townships, the authors determined classification results of agricultural land and construction project site selection in cultivated land requisition-compensation balance, the spatial location and the quality gradation of the occupied cultivated land. The weighted average method was used to calculate the comprehensive classification and total amount of the cultivated land. On the basis of selecting land development and consolidation project which met requirement and was checked, scope of land development and consolidation, land use division and present land use map should be stack processed. Then according to principles of cultivated land supplement, the location of supplementary cultivated land should be identified. Based on principles of compensating basic farmland and stack process of spatial location, quality grade and land use plan map should be identified for basic farmland in complementary region and the spatial location of complementary basic farmland. On the basis of solving index transaction, the method of compensating cultivated land and basic farmland could be used to the cultivated land requisition-compensation balance in different regions. The intended land use area of Ordos - Anping - Cangzhou Gas Pipeline project (Yuxian Section) is 31.6080 hm2, among which the occupied basic farmland is 7.9392 hm2. The comprehensive grade of the occupied basic farmland was calculated as 13 with the weighted average method. The reasons for choosing Yuxian section as the complementary cultivated land are as follows: 1) This piece of land was other grassland before development, while after development, the area of the checked new dry land is 37.9693 hm2 and the grade is 13. That 7.7000hm2 of the new dry land is used to implement the cultivated land requisition-compensation balance, which meets the quantity and quality requirements of complementary cultivated land. 2) There are large tracks of ordinary farmland around the block, which can be connected with the location of complementary cultivated land, thus the cultivated land can be concentrated scaled. Based on stack process of classifying maps of agricultural land use and maps of overall land use planning in towns and townships, the location of complementary basic farmland could be determined. The reasons are as follows: 1) The agricultural land grade in this block is 13. The grade of complementary basic farmland meets the requirement of the grade of occupied basic farmland. 2) It is close to Dongtou village. For the village''s future development without limitation, a not very close block is chosen. 3) This block is connected with designed basic farmland, which meets the requirement of land concentrated scaled. The results show that:1) Based on the results of agricultural land gradation, the quantity and spatial layout of the occupied cultivated land can be accurately positioned. After calculation and analysis, the gradation of the occupied cultivated land can be determined as well. 2) Based on the results of agricultural land gradation and land consolidation, the quantity, quality and spatial layout of the supplementary cultivated land and the ordinary farmland which is designed as the basic farmland can be determined; it can be ensured that the gradation and quantity of the supplementary cultivated land are not less than those of the occupied cultivated land; the gradation and quantity of supplementary basic farmland are not less than those of the occupied basic farmland; and the supplementary cultivated land and other cultivated land are concentrated scaled. 3) Because of imperfect trading mechanism, there exist sharp differences in target price in cultivated land requisition-compensation balance among different regions. On the basis of solving index transaction, the method of compensating cultivated land and basic farmland can be used to the cultivated land requisition-compensation balance in different regions, which can provide a more scientific approach for the cultivated land requisition-compensation balance. In summary, based on the classification results of agricultural land and the results of land development and consolidation, the supplement of cultivated land and basic farmland can be rationed and located accurately. |
