广东惠州惠南湖重点区土壤质量评价

Soil Quality Evaluation in Huinan Lake Key Area of Huizhou,Guangdong Province

土壤质量关系到居民身心健康及工农业发展,日益受到人们重视。通过对惠州市惠南湖重点区进行土壤质量评价,共采集116件表层土壤样品,测试分析了有机质、pH等13项指标。评价结果显示,研究区内土壤以三等为主,占比达到60.09%;一等、二等土壤分布面积较小,合计占比仅为20.36%;四等土壤占比为18.81%;五等土壤占比为0.74%。区内土壤环境质量总体优良,影响区内土壤质量的最主要因素是土壤中养分元素的大面积缺乏。该研究成果对指导当地土壤资源开发利用具有重要意义。

Soil quality is related to the physical and mental health of residents and the development of industry and agriculture,and has been paid more and more attention.A total of 116 surface soil samples were collected to evaluate soil quality in Huinan Lake,Huizhou,and 13 indexes such as organic matter and pH were tested and analyzed.The evaluation results showed that the soil in the study area was mainly gradeⅢ,accounting for 60.09%.The distribution area of first and second class soil is small,accounting for only 20.36%.The fourth grade soil accounted for 18.81%;The proportion of fifth grade soil was 0.74%.The soil environmental quality in the area is generally good,and the main factor affecting the soil quality is the lack of nutrient elements in the soil.The research results are of great significance to guide the development and utilization of local soil resources.
