江苏省沿海地区盐田土地整治为耕地的可行性评价

通过对江苏省沿海地区盐田土地整治的可行性评价和限制性因子分析,在实地调查的基础上,以盐田整治为耕地作为评价目标,从自然条件适宜性、经济支撑可行性、工程实施可操作性、综合效益可增性和生态环境敏感性5个方面构建了评价指标体系。将研究区盐田土地整治分成4种适宜类型区,并确定了盐田整治为耕地的限制性因素。结果表明,江苏省近期适宜整治的盐田主要分布在连云区东南部及灌云县灌西盐场境内、灌河以南地区、射阳河南岸射阳盐场境内、东台市东部和如东县东南部,而财政收入、与海岸线距离、相对海拔高度则是影响江苏省盐田整治可行性的首要、次要和第3限制性因子中的重要影响因素。

Feasibility Evaluation of Salt Field Reclamation for Arable Land in Coastal Areas of Jiangsu Province

The purpose of this paper was to evaluate the salt field reclamation feasibility and analyze the limiting factors in coastal area in Jiangsu Province, and to provides support for spatial selection and technology design for salt field reclamation, and to increase the sources and the ways of arable land supplement and ensure the effective implementation of the coastal development strategy. On the basis of field survey, taking coastal waste salt field remediation for arable land as evaluation objective, the construction of the evaluation index system was based on natural conditions suitability, feasibility of economic support, implementation of the project operability addition of overall efficiency and ecological sensitivity. Meanwhile, the study area of salt field reclamation was divided into four suitablity types, and the limiting factors of salt field reclamation were determined. The results showed that, in the next few years, the areas of suitable remediation salt fields are mainly distributed in the southeastern of Lianyun district, Guanxi saltern of Guanyun County, the south of the Guanhe River, Sheyang saltern in the South Bank of Sheyang River, the eastern part of Dongtai City and the southeastern part of Rudong County. The main limiting factors of salt field reclamation feasibility in Jiangsu Province are government receipt, the distance from coastline and relative altitude.
