However, relatively single product and homogenized development model make competition gradually intensify, and many once glorious rural tourist destinations gradually decline. Xishan District of Kunming City of Yunnan Province is taken as research object in this paper. Via literature research, field survey and depth interview, development process, status quo and existing problems of its rural tourism are deeply explored. Based on above research results, development idea, strategy and countermeasure for quality improvement and effect increase of traditional rural tourism destination are proposed, and cooperative development, mutual benefit and win-win are taken as the ultimate development goals.展开更多

The relative improvement of efficiency in use of the invested factor marks the economic growing quality.So,in order to understand the economic growth quality of China to some extent, it must analyze Chinese factor input and aggregative productivity. This is the main topic that this text will be probed into.展开更多

[ Method] The coats made of pelypropylene were put on fine-wool sheep after shearing and taken off next year, The effects of coats on structure, production and quality of wool f bers, wool sweat secretion, percentage of clean wools, impurities and wool textile process in fine-wool sheep were observed, [ Result] After the sheep were dressed one year later, the average fiber length was increased by 0.33 cm （P 〈 0.05） ; the percentage of clean wools was increased by 12.44% （ P 〈 0.01 ） ; the yield of clean wools were increased by 0.44 kg （ P 〈 0.01 ） ; the wool grease content was increased by 6.44% （ P 〈 0.01 ） ; the length of polluted staple was decreased by 3.10 cm （ P 〈 0.01 ） ; and the impurity content was decreased by 21.25% （ P 〈 0.01 ）. [ Conclusion] Coats remarkably improve quality of wool fibers and production performance in fine-wool sheep.展开更多

文摘As one of important channels in rural revitalization and development, rural tourism obtains a lot of remarkable achievements in rural development. However, relatively single product and homogenized development model make competition gradually intensify, and many once glorious rural tourist destinations gradually decline. Xishan District of Kunming City of Yunnan Province is taken as research object in this paper. Via literature research, field survey and depth interview, development process, status quo and existing problems of its rural tourism are deeply explored. Based on above research results, development idea, strategy and countermeasure for quality improvement and effect increase of traditional rural tourism destination are proposed, and cooperative development, mutual benefit and win-win are taken as the ultimate development goals.
