Trichogramma showed high control efficacy on cotton bollworm eggs after three times of release both in the second and in the third generation bollworm periods. The parasitism on the second and third generation bollworm eggs were 66.0%-70.7% and 76.0%-81.2%, respectively, which were significantly higher than that in the control (second generation: 7.0%-12.3%, third generation: 5.2%-7.4%). And the injury rate of cotton buds and bolls in the second and third generation bollworm were 2.2% and 3.1%, respectively, which were significantly lower than that in the control (second generation:8.5%, third generation: 20.9%). In the second generation bollworm period, number of bollworm eggs or larvae in the Trichogramma released cotton field did not differ to that in the chemically controlled field. But in the third generation, there were significantly less bollworm eggs and larvae in the Trichogramma released cotton field. There were more predators in the Trichogramma released cotton field. These results indicated that cotton boll worm in the transgenic insect-resistant cotton field can he effectively controlled by mass-releasing of T.

结果发现：棉铃虫卵在棉株不同部位的分布差异较大，2代棉铃虫卵主要分布在叶正面、叶背面和茎尖，3代棉铃虫卵主要分布于蕾铃；在放蜂田，赤眼蜂对棉株不同部位棉铃虫卵的寄生率差异较大，2，3代棉铃虫时期对叶正面、叫背面、茎尖、蕾铃的棉铃虫卵寄生率均较高，对叶柄和茎杆处卵的寄生率较低；并以3代棉铃虫时期的寄生率较高；在2，3代棉铃虫时期分别连续释放3次赤眼蜂，对棉铃虫具有很强控制作用，2，3代棉铃虫卵的被寄生率分别为66.0%~70.7%和76.0%~81.2%，均显著高于化防田的自然寄生率（2代：7.0%~12.3%，3代：5.2%~7.4%）；蕾铃被害率分别为2.2%和3.1%，均显著低于化防田（2代：8.5%，3代：20.9%；2代棉铃虫时期，放蜂田和化防田的棉铃虫卵量和幼虫数量差异均不显著，但3代棉铃虫以后，放蜂田棉铃虫卵量和幼虫数量均显著低于化防田，且放蜂田的捕食性天敌数量显著高于化防田。

In sphere approximate, GPS/Gravity-BVP is Neumann problem over exterior spherical domains. Then the natural boundary reduction, suggested by Feng and Yu, is applied to deal with the three dimensional problems. By expansion in spherical harmonics, the natural integral equations of harmonic problems over exterior spherical domains are obtained. Meanwhile, a numerical method for solving geodetic BVP is developed.

A political economist then naturally understands globalization as part of the process of spatialization, which means the process by which in our world, capitalism annihilate or at least transforms space with the market or what Max called time, spatialization.

政治经济学家很自然地就能理解全球化是空间化过程的一种形式，空间化过程是指在我们世界里，资本主义用市场或者是用马克思所说的时间消灭或是至少转换了空间障碍，这就是空间化。

This paper mainly includes two parts The first part falls into three main sections. First, it analyses the formative causes of the Chinese traditional house interior display art through five aspects, including the structure and forms of Chinese traditional architecture, the productive mode of Chinese traditional society, Chinese traditional philosophy, the idea of ethics and grading and custom of Chinese traditional society. Second, it briefly introduces the history of Chinese traditional house interior display art's development. Finally, it focuses on the analysis of Chinese traditional house interior display art's design ideas and concludes that its design ideas embodies the five sides as follows: respect for nature and imitate artfully nature, practical-oriented and function incorporated into form, images of space of what the theory and practice forms, balanced natural pattern of the display, artifacts with the thoughts and respect for poetic imagery. Another part of the article further researches on the application of Chinese traditional house interior display ideas to the contemporary home display, and leads to the author's view, that is that each era should has its own character when it inherits the traditional culture. What's more, the contemporary Chinese-style home display design not only have to take over the spirit of the tradition but also have to give full consideration of the contemporary aesthetic concepts, principles and methods. In the 21st century, humanistic care is greatly proponed in the interior design. The interior display art should develop towards the ecological, personalized and comfortable direction and the cultural dimensions. It should absorb the traditional cultural elements to decorate contemporary living space. In order to upgrade the simple and primary "appearance likeness" to a higher level of "spirit likeness", it must effectively grasp the poetic imagery of space, which can reach the artistic effect of "both appearance and spirits".

本文的重点内容有两部分：一部分是从中国传统建筑的结构形式、中国传统社会的生产方式、中国传统的哲学观念、中国传统的伦理等级观念、中国传统社会的风俗习惯等五个方面简单分析了中国传统民居室内陈设艺术形成的原因；简要介绍了中国传统民居室内陈设艺术的发展过程；着重对中国传统民居室内陈设艺术设计理念的具体内涵进行了深入的分析，总结出其设计理念集中体现在五个方面，即崇尚自然与巧法造化、实用为本与文质彬彬、虚实相生的空间意象、均衡自然的陈设格局、器以载道与以境为尚；另一部分是对中国传统民居室内陈设设计理念在当代居室陈设设计中的应用作了较深层次的探讨，并提出了自己的见解，即每个时代对传统文化的继承都应该呈现出自己的特色，当代中式风格的居室陈设设计既要秉承传统民居室内陈设艺术的设计精髓，又要充分考虑当代审美观念、原则和方法的融入。21世纪，室内设计大力提倡人文关怀，具体到室内陈设艺术设计上，应该向生态化、个性化、舒适化和文化层面发展；吸收传统文化元素装饰当代居室空间，要有效地把握空间意境，使当代中式风格的居室陈设设计从简单、初级的&形似&上升到较高层次的&神似&，进而追求&形神兼备&的艺术效果。

Comparing the landscape types of 1995 with that of 2005, we find out that:①the natural arbors are decreasing, with patches more fragmentation, size more odds, shapes more complex;②the area of natural shrubberies is increasing, with patches less fragmentation, shapes more simple and formulary ,the size of patches more even;③the area of natural grasses is increasing, with patches less fragmentation, shapes of patches more odds;④the area of timbers is increasing, with patches more dominance in landscape, more connectivity;⑤the area of Eucalyptus increases, with patches less fragmentation, shapes of patches more complex , more convergence, more connectivity;⑥the area of orchards is increasing, more connectivity;⑦the patches of the rubber is becoming more assemble, more connectivity, more formulary;⑧the area of plowland increases;⑨the area of reservoirs, rivers and ponds increases, with patches more assemble;⑩the area of cities decreases, with patches more dispersing, with shape more complexthe area of countries increases, with patches less connectivity, more dispersing, with shape more complex; the patches of the rest lands are more dispersing, with shape more complex;(3)In the process of economic development in the upper reaches of the Changhuajiang river watershed, a series of the ecological environment problems have appeared because a lot of landscape function broke off, and the connection of human landscape with natural landscape decreased, which aroused by the fragmentation of natural and semi-nature landscapes increased, the stability of the landscape structure decreased, as well as stress of human disturbance, resource and environment upon the landscape increased gradually.
