- 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.
