| 摘 要： | 调查和测定了调查区域土壤剖面的基本属性、养分和重金属以及水质pH和重金属的含量。结果表明,土壤发育层次受坡积、残积和洪积物的影响,其发生层差异明显;随着土层深度的增加,土壤有机质、全N、速效P和速效K的含量呈逐渐降低趋势,且各养分之间存在一定的相关性;土壤重金属Zn、Ni、Cr、Cu含量均符合土壤环境质量标准,综合指数P综≤0.7,评价为安全,达到国家土壤环境质量(GB 15618-1995)一级标准;水质重金属Pb、Cd、Hg、Cr的含量均符合国家(GB/T 19630.1-2005)规定的有机类养殖业畜禽饮用水标准。因此,在惠州山区的调查区域内,利用山区地形推行畜禽养殖的模式,是发展有机畜禽业的理想场所。

| Abstract: | Soil and water quality in Huishan district of Huizhou city were valued through determining soil profile characteristics, nutrient and heavy metal contents in soil and water. The results showed that different deposits affected soil development. Soil organic matter, total N, available P and K decreased with soil depth. And there were close correlation among soil nutrients. Zn, Ni, Cr and Cu contents in soil were lower than the limits in the environmental quality standard for soils (GB 15618-1995), and the soils were valued as 1st level and safe. Heavy metal contents in waters were qualified for the drinking water quality standards for livestock (GB/T19630.1-2005). Therefore, Huishan district is one of the best places for developing organic livestock farming. |
