- 摘要:
- 土壤养分是植被恢复生长的物质基础，文章以六盘水钟山区老鹰山镇不同年限退耕地为研究对象，以中度石漠化地为对照，采用空间代替时间的方法对其土壤养分演变动态进行测定分析，并运用均方差决策法对不同年限退耕还林地的土壤养分恢复状况进行了定量评价。结果表明：该区退耕还林地土壤养分与退耕时间之间呈现正相关关系。坡耕地退耕还林后，退耕坡耕地土壤养分指数较对照中度石漠化参照地高出6~14倍，土壤养分与中度石漠化对照地相比均有一定程度的提高，且随退耕还林年限的递增总体呈增大趋势。
- Abstract:
- Soil nutrient is the material foundation for vegetation restoration and growth. The method of space representing time scale is used to examine the soil nutrient dynamics with moderate rocky desertification as background in the different reclaimed terms at Hawks Town, Zhongshan District of Liupanshui City. Standard deviation decision-making is used for different period of forest rehabilitation from slope agricultural land on the restoration of soil nutrients for a quantitative evaluation. Correlation analysis showed that soil nutrient has positive correlation with period of the forest rehabilitation from slope agricultural land. The results of quantitative evaluation showed that the soil nutrient index of slope converted farmland is 6～14 times higher than the moderate rocky desertification, and its soil nutrients could be restored significantly and increased with the growing of the abandoned terms.
