查询词典 cash crop

Results show 1 the total water requirement of the crops in the Jinghe Watershed is 740543.20×10^4 m^3, accounting for 41.58% of the total water requirement of the region; 2 of the two major groups of crops, grain crops are higher than cash crops in water requirement quotas; and among specific crops, vegetables, melons, rice and cotton are higher and sunflower, potato and benne are lower than other crops; 3 water requirement per hectare varies from county to county with the highest being 5682m^3hm^(-2), in Jingyang County, and the lowest 4022 m^3hm^(-2) in Dingbian County, averaged to 4 583 m^3hm^(-2), but the water requirement quota of a crop does not vary with the county, so calculation of water requirement quota of a county is closely related to its cropping structure; and 4 because of serious waste of water in farming, the actual water consumption in agriculture in the region is much higher than the calculated crop water requirement.

结果表明，泾河流域农作物需水量总计740543.20万立方公尺，农作物需水占总需水量的比例较高，为41.58%。粮食作物需水定额较经济作物高；就具体作物而言，菜、瓜类、水稻、棉花等需水定额较高，向日葵、薯类、胡麻等较低。各县单位面积需水量差异较大，平均值为4583立方公尺hm^(-2)；泾阳县最高，为5682立方公尺hm^(-2)，定边县最低，为4022立方公尺hm^(-2)。由于事先设定大多数作物的需水定额不随县的改变而改变，因此需水量与作物结构密切相关。农业用水浪费严重，使泾河流域农作物实际用水量远高于需水量的理论计算值。

The thesis is based on income question, forest coverage rate and grop production.to beging with, date envelopment analysis is proved that it can be applicated into grain for green in shan-bei district, and then in view of the fact, seven esential factors which have influence on the project are found out: expense of dam, expense of crop,expense of cash tree ,expense of defense tree,other economic crop,expense of grass and graziery;and the output factors include:income of gdp,pure income per captia,the area of decreasing land loss,graziery income ,crop production,income of tree,the totle income of economic crop.after the date of each facts are puted into dea model,unefficiencial decision making units found.the data that are got through adjusting unefficiencial dmus dy dea can offer guide in shanbei district upgrading of an industrial structure.at the same time ,taking into account some possible problems in or after grain for green in shan-bei district,the thesis bring out some propesal to improve the circumstance,enhance the life level and putthe relation of population,resource and circumstance into a healthy orbit.

论文以解决陕北地区的收入问题，植被问题以及粮食产量问题为出发点，首先从理论上分析了包络分析方法在陕北地区退耕还林中运用的可行性，然后结合陕北地区目前的实际情况，综合分析出影响陕北地区退耕还林的关键的七个因素作为输入指标：水利水保设施投入，农作物投入，经济林种支出，防护林支出，其它经济作物，草类支出，畜牧业投入；以退耕还林所要解决的最终问题作为输出指标：GDP收入、农民人均纯收入、水土流失减少量、牧业总产值、粮食产量、林业总产值、其他经济作物总产值。将各指标所对应的数据代入模型后，通过分析求解得出非有效的决策单元，再运用包络分析方法的一些基本原理对非有效的决策单元进行调整，由此所得的数据对陕北地区的实际投入具有很好的指导意义。同时，又针对陕北地区在退耕还林过程中以及之后可能面临的困境，提出了一些建议和对策。最终使得陕北地区的投资环境尽快得以改善，使农民尽快脱贫致富，使人口、资源、环境的关系尽快纳入良性循环的轨道上。
