Abstract

Spatio-temporal variation characteristics of soil pH, soil organic matter, total nitrogen, available phosphorus and available potassium contents were determined in Wenling City of Zhejiang Province in 2006 and 2017, respectively, using the analysis methods of mathematical statistics and inverse distance weighting spatial interpolation. The results showed that the soils presented a certain acidification trend with a decrease in soil pH of 5.40%. Soil organic matter (SOM) and nitrogen, phosphorus and potassium contents showed an overall increasing trend. Available phosphorus and available potassium contents increased significantly, with increased ratios of 50.34% and 26.23%, respectively. SOM and total nitrogen contents also increased to a certain extent, increasing by 13.97% and 10.76%, respectively. The results of spatial analysis showed that the soil pH decreased in the west of Wenling, while increased in the east of Wenling. Total nitrogen contents of the soils decreased in the north of Wenling, while increased in the south of Wenling. The available phosphorus and available potassium contents increased significantly. The above results indicate that fertilizer application will be implemented according to soil pH, the abundance and deficiency of nitrogen, phosphorus and potassium, and the law of fertilizer requirements for crops. The improvement of the soil quality and soil sustainable development will be focused on.

Key words： soil pH soil organic matter nitrogen, phosphorus and potassium nutrients spatio-temporal variation characteristics

浙江省温岭市土壤pH及氮磷钾养分时空动态变化特征

采用数理统计和反距离权重空间插值分析方法，分别对浙江省温岭市2006年和2017年间隔11年的土壤pH、有机质、全氮、有效磷和速效钾含量数据进行时空动态变化趋势分析。结果表明：土壤呈现一定的酸化趋势，pH下降达5.40%；土壤有机质和氮磷钾养分总体上呈现增加趋势，其中土壤有效磷含量增幅最为明显，增幅高达50.34%；其次是土壤速效钾，增幅达到26.23%；同时，土壤有机质和全氮含量也有一定程度的增加，增幅分别为13.97%和10.76%。空间分析结果表明，土壤pH总体上呈现西降东升的趋势，土壤全氮含量总体上呈现北减南增现象，土壤有效磷和速效钾含量总体上都显著增加。因此，在后续全市域土壤培肥过程中，需依据土壤pH及氮磷钾养分丰缺情况，并结合所种作物的需肥规律，进行合理平衡施肥，实现全市耕地土壤质量的全面提升和土壤的可持续发展。
