| Abstract: | Muyu reservoir, located in the Shandong peninsula of China, is a large valley reservoir. Due to serious vegetation degradation and soil erosion surrounding the reservoir, the environment in the watershed was deteriorating before the implementation of eco-restoration engineering and had lost 15% of its water storage capacity. The eco-engineering construction aims to conserve water and reservoir surroundings through afforestation, to avert mud-sand deposition, and to raise agricultural benefits ecologically and economically, by forest-grass eco-restoration engineering for soil and water conservation. By using appropriate eco-engineering methods, an eco-restoration engineering model and forest-agronomy-livestock-fishery integrated shelter system, which realized the beneficial conservation and recycling of Muyu reservoir water environment, have been set up. The eco-restoration engineering mainly consists of eco-orchard engineering and techniques, IPM methods in integrated fruit farming system, agro-forestry techniques in land runoff eco-engineering and terrestrial-aquatic-integrated farm eco-engineering and techniques. By an 8-year construction, a 150-ha eco-restoration engineering in Muyu reservoir watershed was established, which brought about an average annual increase of 21% vegetation coverage, 70.9% total agricultural output value and 80% income, as well as a decrease of 50% mud–sand deposition and 50% chemical pesticides and fertilizer in the last 5 years. |
