The Economic Benefit Evaluation About The Planting Patterns Of Grain,Cotton And Fruit In The Three Regions Of Southern Xinjiang

At present,the Xinjiang red jujube,apricot planting area are ranking first in the country,walnut planting area is the third in the nation.The specialty horticulture has become a new pillar industry that farmers get rich in Xinjiang.The Characteristics horticulture area of the Three Regions of Southern Xinjiang accounts for 12.88% of the area of the Xinjiang characteristic horticulture,which makes it become the main force of Xinjiang Characteristics horticulture.Therefore,largely to develop characteristics horticulture is bound to affect the local food crops and other crops grow.Taking fruit intercropping can weaken the adverse effects that is due to vigorously developing horticulture crops and other crops,at the same time,improving the land utilization rate,and it can improve the local farmers’ income.Taking fruit intercropping is active in the local promotion,and formed a variety of patterns.So it is not sure which is the most suitable for local planting pattern.Therefore,this article is from the perspective of economic benefits,through to evaluate the local economic benefits of different models,discussing the most suitable for the development of the local grain intercropping mode.It has very important significance in economic development,social stability,agricultural system structure optimization and rich minority areas out of poverty of the Three Regions of Southern Xinjiang,Based on the analysis of field investigation data with the input-output indexes and so on,taking descriptive analysis of economic benefit on sinterplanting model.The results shows that the economic benefits of fruit trees is higher than fruit tree intercropping crops,which is higher than food crops and cash crops.Visibly,Grain intercropping fruit has certain influence on fruit trees itself and intercrop.In this paper,selected twelve indexes static and two dynamic indexes,through the Improved Principal Component Analysis(PCA) to get the economic benefit evaluation on 24 kinds of grain intercropping mode,reviewing the evaluation with the Entropy Value Method,both of which has passed the Kendall-w Concorde coefficient method,through Integrated Comprehensive Evaluation Method to get the final result:The fruit trees in sapling stage,the economic benefits of almond-cotton>walnut-wheat-corn>walnutcotton>red jujube-cotton >red jujube-wheat-corn.Visibly, when the fruit trees in sapling stage,almond-cotton,walnut-wheat-corn is suitable for promotion mode.Fruit trees in the early fruiting not suitable for intercropping cotton.The fruit trees in the provinces,walnut-wheat>walnut-corn>walnut-wheat-corn>Almond-cotton>Walnut-cotton>almond-wheat-corn>the almond trees-wheat-corn>cotton>almond-cotton>red jujube-Wheat>walnut- wheat-soy beans>red jujube-wheat-green beans>wheat-corn>corn>wheat.Visibly,fruit trees in the provinces,the walnut-wheat,almond-cotton,almond-wheat-corn,red jujube-wheat is suitable for local promotion mode.
