摘要:

开展耕地占补平衡是国家严守1.2亿hm2耕地红线的重要举措,但重数量轻质量的现象普遍存在。该研究对浙江省5个县(市、区)近年来验收通过的补充耕地项目进行取土化验、评定质量等级,结果表明,补充耕地地力状况总体较差,平均耕地质量等级为7.44等,土壤有机质、全氮、有效磷、速效钾含量均处于中等偏下或较低水平,土壤呈弱酸性,并存在项目设计不合理、后期管护不到位等情况。提出加强立项论证、增加资金投入、建立联合验收机制、开展快速培肥等建议,为提升补充耕地质量提供参考。

Abstract:

Requisition-compensation balance of cultivated land is an important measure for the country to strictly adhere to the red line of 0.12 billion hm2 of cultivated land. However, the phenomenon of putting the quantity ahead of quality generally exists. We tested the soil and assessed the quality grade of the supplementary cultivated land projects that had passed the acceptance inspection in five counties (cities, districts) in Zhejiang Province in recent years. The results showed that the overall fertility of the supplementary cultivated land was inferior, the average quality grade of supplementary cultivated land was 7.44, and the average values of soil organic matter, total nitrogen, available phosphorus and available potassium were all at medium to lower level, the soil was weak acidic. Besides, there were some problems such as unreasonable project design, inadequate post-management and so on. Countermeasures were put forward to improve the quality of supplementary cultivated land, such as strengthen the argument of project establishment, increase capital input, establish joint acceptance inspection mechanism, and rapid fertilization.
