Analyzing water balance of the ecosystem (area for collecting rainwater) in geomorphic unit and the hydrologic process

taking the rainwater allocation proportion

rainfall runoff volume

losing quantity of soil and nutrients in different sloping land ecosystem as parameters

considering the requirement of water balance of geomorphic unit in the area for collecting rainwater

irrigation in the sloping land

the bearing capacity to the rainwater erosion of different sloping land ecosystem and the influence of the rainwater travel from slopping land on the environment and the water-logging-disaster area as constraint condition

construction of agro-forest multi-ecosystem in hilly sloping land of red soil is fitted out with a view to water balance and reasonable land utilization structure: artificial afforestation is 30%

15% for sown pasture

30% for tea garden

20% for cultivated land

and 5% for natural protection area. It characterizes as that it offers gist for construction of agro-forest multi-ecosystem in hilly sloping land of red soil with a view to water balance and suitable land utilization structure; it embodies the thought of great agriculture

corrects the tradition utilization of one unitary ecosystem in hilly slopping land; the proportion of land utilization accords with the development of social economy

can basically achieve the requirement of foodstuff security to plough land prolongation at the peak of population. This structure meets the requirement of which not only using slopping land to collecting rainwater for keeping water balance in geomorphic unit (area for collecting rainwater) ecosystem

but also the sustainable protection of agro-forest multi-ecosystem in the slopping land.
