丘陵山坡地生态治理模式探索——以浙江省建德市平山顶生态园为例

Exploration of Ecological Management Model on Hilly Slope -Take Eco-Peak Garden in Jiande City of Zhejiang Province as an Example

在实践中提出了"三型两配套"的丘陵山坡地治理模式,并在浙江省建德市平山顶生态园进行试验示范。与治理前相比较,植被覆盖率从25%提高到85%以上,年水土流失总量从2042t减少到430t,土壤侵蚀模数从3003t/km2.a下降到632t/km2.a,农民经济收入提高了15倍以上,使该示范区的坡地生态系统进入可持续发展的良性循环中,找出了水土保持走生态经济和资源开发之路的有效途径。

The article selects Peak-ecological garden in Jiande city of western Zhejiang to explore ecological and economic of water and soil conservation and resources development approach. The garden utilizes a model of three types and two complementary. After the management, the land cover increases from the original 25% to more than 85%, the total amount of annual soil erosion reduced to 430 t from 2, 042 t and the soil erosion modulus declines to about 632 t/km^2.a from original 3, 003 t/km^2.a and the income of farmers have increased more than 15 times, Causing this model district the slope ecosystem to enter the sustainable development in the positive cycle, we have discovered the conservation of water and soil ecology economy and the effective way of resources development as well.
