该地区的农民不得不在这块贫瘠的土地上挣扎谋生。 - In the eroded infertile soils of the yangtze river watershed there was an obstacle to the use of “ soil reservoir ” , that is , the storage capacity of “ soil reservoir ” had been severely lost because of soil erosion
长江流域的侵蚀劣地“土壤水库”需要承受更多的拦蓄雨水任务，但这些侵蚀劣地土壤区存在着调用“土壤水库”的障碍。 - Besides policy factors , five methods of cost - cutting of biodiesel are reviewed , including new raw material with higher oil content , shorter regeneration cycle , which is suitable for infertile soil and different climatic conditions ; heterogeneous catalysts ; new technologies ( e . g . supercritical methanol and ultrasonics ) ; higher added value utilization of by - product glycerin with simple method ( propylene oxide chloride , 1 , 3 - propanediol , pyruvic alcohol etc . ) and moderate scale of production
摘要综述了除政策因素外，降低生物柴油生产成本的5种方法：选择含油率高、再生周期短、适应贫瘠土地及不同气候条件的新型植物原料；研究新型固体催化剂；引入新工艺（超临界法和超声波法） ；使用比较简便的方法将废弃的甘油转化为高附加值的产品（环氧氯丙烷、 1 , 3 -丙二醇、丙酮醇等）以及适度生产规模等。 - These measures include : rehabilitation of vegetation with preserving soil and water on the eroded infertile soils , the entrance to “ soil reservoir ” dredged by controlling with different eroded soil types , using “ soil reservoir ” of the upper reaches of the yangtze river bigger much more than the reservoir of the three gorges
充分调用“土壤水库”实现长江流域防洪减灾的措施应包括建立保土保水的地表植被系统，分类整治侵蚀劣地土壤，疏浚入渗“土壤水库”的通道，以及重视调用一个比三峡水库库容大得多的“土壤水库” 。
