- 摘要:
- 采用LFA方法从景观内部构成和土壤表层状况两个方面对陕北黄土丘陵区典型不同林龄人工刺槐林、人工侧柏林、人工柠条林和撂荒草地进行了景观功能评价，探讨陕北黄土丘陵区不同退耕时期人工植被景观对区域土壤性能改善情况及水土保持作用。分别在4种植被景观类型内布设3条不短于50 m样线，在样线上调查斑块和非斑块种类及数量，并在斑块和非斑块内设置1 m2调查区进行了土壤表层评价。结果表明：（1）各景观类型中，斑块百分比及斑块面积大小顺序为人工柠条林 > 撂荒草地 > 人工侧柏林 > 人工刺槐林。（2）随着退耕年限的增加，人工刺槐林及侧柏林景观特征指标及斑块面积指标显著降低（p<0.05），人工柠条林及撂荒草地景观特征指标及斑块面积指标有增加趋势但是不具显著性。（3）人工刺槐林和人工柠条林土壤健康指标最高，对土壤性能具有较强改善作用，人工侧柏林对土壤性能改善作用处于中等水平，撂荒草地土壤健康指标最低。（4）随着退耕年限的增加，人工刺槐林、人工柠条林对土壤性能具有显著改善作用，人工侧柏林和撂荒草地对土壤性能的改善作用不明显。综上，人工刺槐林、人工柠条林对改善生态环境，减少水土流失具有显著作用，人工侧柏林的土壤改善和水土保持作用不明显，撂荒草地能够对土壤性能起到改善作用，但处于较低水平。
- Abstract:
- Landscape function analysis method (LFA method) was used to assess landscape internal distribution and soil surface conditions in locust, arborvitae, Caragana, wasteland landscapes with different restoration years in loess hilly region north of Shaanxi Province to discuss the soil condition improvement and water conservation abilities of 4 landscape types in different restoration years. To reach the research goal, 3 sample lines longer than 50 meters were set in every plot in each of 4 landscape types. Then the type and number of patches and interpatch were investigated on each sample line and soil surface investigation was done in 1 meter square query zone within every type of patch and interpatch. The results showed that:(1) within four landscape types, the order of patch proportion and patch area was Caragana > wasteland > arborvitae > locust; (2) with the increasing of restoration year, the landscape organization index and patch area index in locust and arborvitae community showed significant decreasing pattern, while Caragana and wasteland community showed increasing pattern; (3) locust and Caragana communities had the highest value in soil health index, showing the highest ability of soil condition improvement, while arborvitae communities showed normal ability of soil improvement, and wasteland had the lowest soil health value; (4) with the increasing of restoration year, locust and Caragana community had significant improvement on soil property, while arborvitae community and wasteland could improve soil property but did not show significance; locust and Caragana communities had significant effect on improving ecological environment and decreasing soil and water losses; landscape function of arborvitae communities could be improved by planting other arbor and shrub species in communities. Landscape function of wastelands can be improved by human disturbance to increase its succession.
