崇州市土壤有机质分布特征研究

Research on Distribution Characteristics of Soil Organic Matter in Chongzhou City

有机质含量是土壤肥力高低的重要指标之一,对作物生长至关重要,该文以崇州市为研究区,对土壤有机质进行了研究,运用经典统计学结合GIS技术,研究耕地土壤有机质空间分布特征和全氮的空间相关关系及分布特征,结果表明,高标准农田建设区有机质含量明显高于周围水稻田种植区域,全区土壤全氮的含量与土壤有机质含量呈紧密的正相关关系。

The content of organic matter is one of the most important indicators of soil fertility,which is essential to the growth of the crops,this paper takes Chongzhou City as the study area,the soil organic matter was studied by using classical statistics combined with GIS technology,spatial distribution characteristics of farmland soil organic matter,spatial correlation and distribution characteristics of total nitrogen were researched,and the results showed that the organic matter content of high standard farmland construction area was significantly higher than that of the surrounding paddy planting area,the soil total nitrogen content and soil organic matter content showed a closely positive correlation.
