- 摘要:
- 在我国干旱、半干旱草原区，草场沙化、退化和水土流失等现象十分严重，要解决这一问题，首先应搞好水土保持生态环境监测。为了客观地分析和评价各项水土保持措施实施后给生态环境带来的效应，在京津风沙源科技支撑项目实施过程中，建立草地水土保持生态技术试验基地，对各项措施实施前后的生态指标进行连续4 a的动态监测。主要研究退化草地围封前后及围栏内不同恢复措施对土壤水分与养分及草场植被的影响。结果表明：围栏前后土壤水分、养分和草场植被都发生了变化，尤其对草场植被的影响极其明显，封育草场的植被盖度较未封育的天然草场植被盖度平均增加58.66%。围栏内不同恢复措施对土壤水分、养分和草场植被也都有明显的影响。
- Abstract:
- Grasslands desertization and desertification and soil and water loss is very serious in arid and semi-arid grasslands in China.For resolving this problem, we should do well in soil and water conservation and ecology monitoring in the first.In order to analyze and evaluate every soil and water conservation measure effects objectively, we dynamically monitored each ecological index for 4 years before and after implementing every measures in our test base, studied the impacts on soil moisture and soil nutrient and grasslands vegetation of enclosure and different recovering measures.Results indicate that the impact on soil moisture and soil nutrient and grasslands vegetation of enclosure is obvious, especially the impact on grasslands vegetation.Vegetation coverage degree increases 58.66% after enclosing.Different recovering measures in the enclosure also influence soil moisture and soil nutrient and grasslands vegetation distinctly.
