| 摘 要： | 通过常规理化分析研究鄂尔多斯市东胜区森林公园的土壤质量状况,结果表明,森林公园土壤容重大,平均为1.50 g/cm3;石砾含量高,除2个黑土样本外,石砾质量分数均大于20%;盐分偏低,Ec值在0.1~0.2 m S/cm;p H值较高,在8.8~9.1,均为强碱性土壤;土壤有机质、碱解氮、有效磷含量均较低,分别在0.6~10.5 g/kg,3.9~43.2 mg/kg,2.6~6.7 mg/kg,且上层土壤含量大于下层土壤;有效钾含量在26.4~87.2 mg/kg,多数处于较低水平,土壤上、下层含量差异无明显规律。总体上说,森林公园土壤质量较差。根据森林公园土壤质量状况,文中提出了加强鄂尔多斯市东胜区绿地土壤科学管理的措施和建议。

| Abstract: | The state of soil quality in Dongsheng District Forest Park in Ordos was investigated and analyzed using routine physico-chemical analysis. The results showed that：（ 1） thesoilbulkdensity is larger,1. 50 g / cm^3 on average;（ 2） gravel content is higher,above 20% except for the two black soil samples;（ 3） soil total salt is lower,with Ec value between 0. 1- 0. 2m S / cm;（ 4） p H value is higher,from 8. 8 to 9. 1,indicating all soil samples are strong alkaline soils;（ 5） soil organic matter,hydrolyzable nitrogen and available phosphorus arelow in content,respectively in the range of 0. 6- 10. 5g / kg,3. 9- 43. 2mg / kg,and 2. 6- 6. 7mg / kg,and the content of upper soils are all greater than the content of subsoil;（ 6） available potassium content is lower in most soils,from 26. 4mg / kg to 87. 2mg / kg,and there is no obvious difference between the upper soil and the subsoil. In general,the quality of soil inthe forest park is at a low level. Based on the results of the investigation,some measures and suggestions were put forward for scientific management of the soil of green spaces in Dongsheng District of ordos. |
