江苏省沿江地区农用地资源质量评价研究

EVALUATION ON THE QUALITY OF FARMLAND UTILIZATION ALONG THE YANGTZE RIVER IN JIANGSU PROVINCE

采用农用地分等中的自然质量分值的计算方法,以实现对地理范围较大,内部自然、经济、社会条件差异较为明显的江苏省沿江地区的农用地资源质量的合理评价。评价结果为:地处宁镇扬丘陵区的该区西部地区农用地的质量复杂多变,各种级别的农用地均有分布且面积比例相差不大;地处太湖平原区的该区南部地区农用地的质量优越;而该区北部地区农用地质量东西两翼较好,中部较差。根据评价结果,从挖掘农用地生产潜力,综合开发利用土地后备资源,提高非农用地经济产出能力,完善农用地与非农用地转换价格约束机制及发展循环产业经济,污染排放源头控制与生产过程中治理相结合等几个方面提出了江苏省沿江地区耕地、生态环境保护与经济协调发展的建议。

In order to acquire the accurate evaluation results of farmlands' quality in the region along the Yangtze River in Jiangsu province, this paper uses the calculation method of natural quality scores to pursue this evaluation. The qualities of farmlands in the western of the research region which is located in Ning-Zheng-Yang hilly area are diverse. Every class of farmlands are distributed here and the differences between the areas of each class are small. The qualities of farmlands in the southern of the research region which is located in Taihu Lake plain area are superior. And the qualities of farmlands in the northern of the research region have the feature as followings: the farmlands in the eastern and western parts are comparatively good, while those in the middle part are comparatively in a low quality. Based on the evaluation results, this paper advances the proposals for the harmonious development between farmland, environment protection and economy elevation from the aspects of exerting the farmland production potentiality, inte grative exploitation of the land resource reserves, enhancing economical output rates of the non-farmlands, consummating the restrict mechanism of conversion between farmlands and non-farmlands, developing circular economy and combination of source control and service to overall production process.
