平潭综合实验区耕地调查与地力评价

Fertility Evaluation of Cultivated Land in the Pingtan Integrated Experimental Area

运用GIS技术和综合指数法对平潭综合实验区耕地土壤进行了耕地调查与地力评价。结果表明平潭综合实验区耕地地力水平较差,以五、六等中产田为主。本区耕地主要限制因素是瘠瘦、干旱、砂化、渍涝、盐分限制、耕地土壤养分不均衡。利用评价结果提出改良措施,以期为平潭综合实验区耕地资源的合理利用提供依据。

This paper evaluates the fertility of cultivated land in the Pingtan Integrated Experimental Area by applying GIS technology and comprehensive index method. The results showed that the fertility level of cultivated land in the Ping tan Integrated Experimental Area is poor, and the main level is from five to six. The main limiting factors are lean, drought, sandy, water logging, salt limitation and mineral nutrients imbalance. Improvement measures are proposed to provide the basis for rational utilization of cultivated land resources of the Pingtan Integrated Experimental Area.
