The Study On The Theory And Practice Of The Agriculture Ecosystem Engineering In Village Xiaofuling

The northward rerouting of southern river median line project takes the water from the Danjiangkou reservoir, by way of Hubei,Henan and Hebei province arrive Beijing and Tianjing city. For insure the security of water quality in the waterhead, the contamination concern must permanently cure. The agricultural pollution is the water resources pollution principal aspect. In order to guarantee the reservoir the water quality and guarantees fanner's basic interest, we must use the ecology method. Optimized disposition agricultural resources. For the region resources superiority, carries on the transformation, the redesign, the combination and the layout to the time and the space. Realize in the agricultural system between each resources component the harmonious most superior combination for achieving the best economic efficiency, the social efficiency and the ecology benefit.This article applies ecology theory union system coupling theory, takes the research object by the Danjiangkou city xijiadian town xiaofuling village, use investigation understanding, the data collection and the fixed-point experiment unifies way, carries on the system diagnosis and the pattern sets up to study the ecology, the economy, the social efficiency, the structure leading, the structure multiplicity, the structure rationality of this system. Last count system coupling degree. Main findings in under:(1) According to systematic theory union coupling theory I have designed three agricultural ecology pattern. Respectively is: Pattern I (Straw stalk-Livestock-Methane), pattern II (Straw-Livestock- Methane- fungus), pattern III(Straw stalk-livestock -Methane - fungus).(2)The design three kind of patterns have all realized the economic efficiency enhancement. The average per person net income respectively is 383.78yuan, 7686.06yuan 和 83338.18yuan. All is higher than Hubei Province and Danjiangkou city average per person net income level. Three kinds of patterns have all realized the garden beautification and the ecology position multi-dimensional use. Labor force intensity poultry raising and edible fungus industry enhance the countryside to leave unused the labor force the use factor. And because the people during participation agriculture coupled system construction, has learned much useful specialized knowledge and the skill. The countryside discipline study, study the technology, gets rich through hard work the atmosphere gradually was thick, enhanced the social efficiency.
