Development of Theory and Practice of Eco-engineering and Thoughts on Present Measures for Slope Control

Development of theories on "near-nature" erosion control were reviewed,connotations of eco-engineering and their present application in various sectors were introduced.There are certain differences between traditional erosion control measures and eco-engineering,particularly in slope control.Present measures in slope control was excessively artificial and simplex,do not reflect "personality" of an ecosystem,they are therefore unstable and unsustainable.Those measures for land rehabilitation,such as large scaled construction of hydrological facilities and basic fields,deviate from principles of "near-natural" slope control theory in terms of their intensity,frequency and costs.The final target of eco-engineering is to set up a near-natural eco-system and insure the harmonious relationship between natural and human being.Therefore it's mostly stable and sustainable.How to apply the eco-engineering methods in our action of soil and water conservation and create a stable,near-natural slope protection system is a primary subjects to every involved researchers.
