| 摘 要： | 采用传统统计和地统计相结合的方法，对面积约720 km2的儋州市橡胶园土壤氮素营养进行了空间变异特征与分区管理技术研究。结果表明，儋州市橡胶园土壤氮素营养缺乏，各土层土壤全氮和碱解氮含量的最大相关距离在39.67～69.24 km之间，基本趋于大块状变异为主；同时，各土层全氮和碱解氮含量基本在第四等级和第五等级；采用空间叠加方法，进行了橡胶园土壤氮素管理分区，整个研究区域可分为10个氮素管理区，每个分区内具有不同的土壤氮素营养状况，需采取不同的氮素营养管理措施。

| Abstract: | Abstract The spatial variability and regionalized management technology of soil nitrogen nutrient in rubber plantation with an area of about 720 km2 was studied using geo-statistics. The results showed the rubber plantations in Danzhou were widely deficient in N. The maximum correlative distance of total N, available N in content in different soil layers were between 36.97 km and 69.24 km. It revealed that the variation in content was developed in large block scale, which is useful to the regionalized management of soil nitrogen nutrients. By overlaying method of the space, the whole investigated region could be regionalized into 10 management units of nitrogen nutrient. |
