From the analysis and discussion of features and significance ofcultivation in the arid winddrift sand areas as well as some currentproblems in the middle part of Ningxia, it can be seen that althoughthe environmental conditions in these areas are poorer for engaging incultivation, cultivation still has an important place in the national eco-nomy, and also plays a decisive role in the stabilization of the liveli-hood of the people, and yet the current problems of cultivation areserious as well.

笔者认为，在我国广大旱作低产区，尤其是农牧交错地区，虽然环境条件有差异，但也都不同程度地存在着类似宁夏中部地区的问题，对于这些问题，期望引起国家有关主管部门的重视，并把这类地区种植业的科学研究纳入我国农业科学研究的轨道。

Or perhaps Mr. Eco's novel is a parody of one of those medieval or Renaissance traveler's tales that have survived over the centuries, like ''The Travels of Sir John Mandeville,'' in which fact and fantasy blended indistinguishably together.

也许，埃科先生的小说只不过是经过几个世纪之后幸存下来的某篇中世纪或文艺复兴旅行故事的拙劣模仿，像&约翰·曼德维尔爵士旅行记&一样，真实和幻想在其中很难被区分开来。

The main reasons caused theses problems are as follows: beyond marine carrying capacity and environment capability by predatory and extensive manners, over-exploitation of bioresources resulted in the disturbance of marine ecosystem and the obstruction of matter and energy circulation. Marine environment pollution and unreasonable oceanographic engineering caused serious damage of marine entironments, weakness of marine eco-functions, and degradation of marine ecosystems. The population explosion as well as the trend of population towards coast inflicted tremendous pressure on marine resources and environment. The weakness of marine laws system and the infirmness of macroscopical control by government policies relulted in unreasonable utilization, inefficient management, and insufficient protection of marine bioresources.

其主要原因是：对海洋生物资源的掠夺性、粗放性开发，造成资源过度利用，超出海洋承载力及其环境容量，物质能量循环出现障碍，海洋生态系统失衡；海洋环境污染和不合理的海洋开发工程，造成生境破坏，生态功能减弱，生态系统退化；人口增长和趋海发展，给沿海资源环境造成巨大压力；涉海法律法规体系薄弱，国家宏观政策调控不力，未能合理利用和有效管理、保护海洋生物资源和海洋环境。
