Abstract: Cultivated land quality assessment and monitoring is one of the most important tasks in China. Cultivated land quality in Southern Jiangsu province has attracted much academics due to new problems such as heavy metal pollution. In our paper, the comprehensive quality evaluation and zoning method of cultivated land by integrating agricultural land classification, land quality geochemical assessments and soil loss prediction based on remote sensing was explored. Here, we restructured cultivated land quality assessment indicators firstly, then integrated with spatial analysis, clustering analysis and the matching analysis of farmland fertility conditions, farmland healthy level and surrounding factors, cultivated land categories of natural quality enhancing, soil pollution remediation, soil and water conservation and superior protection were established. Later, the reclamation paths according to cultivated land quality classification were discussed.#br#The empirical study in Southern Jiangsu showed that less than 65% in the cultivated land was healthy and fertilized, nearly 30% in the cultivated land is covered by poor soil, and over 5% in the cultivated land is threatened by the heavy metal pollution and soil erosion. Concretely, healthy and fertile farmland is mainly distributed in Taihu lake plains and flatlands along the Yangzte River which is in the eastern part of Mao Mountain. The cultivated land in the western part of Mao Mountain is relatively poor, and the heavy metal pollution and soil erosion indexes of farmlands in western part of areas long the Yangzte River and eastern part of Tahu lake is relatively high compared to soil environmental standard. So, it can be argued that agricultural production in southern Jiangsu is likely to meet with environmental risks which are related to cultivated land quality in some senses, and it may be a huge challenge to people's healthy in this area. We points out that farmlands reclamation strategy should be carried out rapidly in order to improve the cultivated land. Our approach improves current cultivated land assessment methods and results can be used for farmlands quality monitoring and management.
