Abstract:
Based on the theory of commercial ecological agriculture,the current ecological economy situation of Majiagou watershed with four optimization ideas were analyzed.Following the ideas,introduced soil conservation theory,set a different mode of development of animal husbandry,and did a linear programming on local economic development.After optimization of the three scenarios,the agriculture,forestry,animal husbandry total revenue improved 20.67%,35.90%,26.15%,the degree of soil erosion decreased 10.68%,8.14%,10.69%,and in the latter two scenarios after optimization of the sheep industry was a great growth,but in absolute terms,because a large proportion of the apple industry,accounting for about 60% of the total,was still the main component of the optimized amount of growth.As it could be seen from the optimization results,opening the understory grass resources moderately under the strict protection of the ecological environment constraints,could effectively promote economic development in the watershed.Also,if the apple industry to achieve meticulous management and improve industrial added value,then making the apple industry development center for the local economy could achieve a win-win goal of the greatest degree of economic development and ecological protection area.
