- Abstract:
-
The hierarchical structure of different forest vegetation has an important influence on the function of water storage and soil conservation, and it also has important significance for maintaining regional ecological balance. This paper takes the water source function area of Maotai in Guizhou Province as the research site. We used the method of field investigation and indoor analysis to analyze the storage effect of different vegetation types, and to discuss the optimal collocation hierarchy of shelterbelt and water conservation forest. The results showed that the canopy interception of different vegetation types increased with the increase of daily rainfall, the interception rate showed a relative decreasing trend, and the stem flow rate and stem flow were increased, and the critical values of runoff and rainfall were found in the bamboo 12.5 mm, the needle-broad mixed forest and the Pinus massoniana 14.5 mm, the Cupressus funebris 18.5 mm. The maximum water holding capacity of different vegetation types showed that the arbor forest was 26.14%, the shrub was 9.26%, the bamboo grove was 7.33%, and the grassland was 6.93%. The study revealed that the more complex the forest structure was, the more remarkable the water storage effect was. Under the natural site condition, the most optimal level structure of the native tree species in the source functional area of Maotai in Guizhou is Pinus massoniana or Cupressus funebris and Choerospondias axillaris or others mixed forest + Myrsine african+ Imperata cylindrica.
