Especially since 1992, its development in foreign trade has skyrocketed because China Shou Gang International Trade Construction Company was approved to be set up. In 1993, it exported 239,700 tons of steel. Its foreign exchange income reached US$630 million, of which the Shou Gang’s self-managed exports took up US$96.98 million. During the展开更多

This region has the highest density in population, industry and towns in China, and the large export-oriented economy makes itself a strategic importance while China enters into international markets. The problems facing to this region include arable land reduction, land degradation aggravation, high percentage of built-up land with high rate of expansion, expanded non-point pollution, deteriorated water quality, decreasing biodiversity, destroyed ecosystems, severe air pollution, frequently occurred acid rain, and multi-pollutants. The important research fields in the near future should include a) influence of high-intensity exploitation of resources on changes of environment quality and its feedback; b) interface processes, key mechanisms and adjustment principles for degradation of water-, land-, and air-resources and environmental quality; c) evolvement processes and nurturing theory of biodiversity and ecological resources; and d) spatio-temporal variation and human-induced effects on regional resources and environment quality. Strategies for sustainable development in the region are as follows: a) controlling to ensure basic cultivated land area; b) enforcing remediation of polluted water environment, and controlling non-point pollution; c) strengthening ecological construction and ecological security; and d) controlling multi-pollution and preventing trace toxic pollutants.展开更多

The products can be produced in batches today. However, application of such materials in apparatus is laggard than developed countries. GMM materials are mainly applied in step motors, linear actuators, ultrasonic systems, sonar systems, valves, precise controls, active vibration damping etc. It is estimated that the near 10 years will be the fast developing period of global GMM market. Global production of GMM materials during 1989 to 2005 is listed in Table 3.展开更多

But the reasons for 2 differential developmental rates within same cohort under varying environmental factors have not been explored. For the purpose, in this study the existence and stability of slow and fast development under 5 photoperiods （i.e., 8L： 16D, 10L ： 14D, 12L ： 12D, 14L ： 10D and 16L ： 8D; light and dark hours per day） and its effect on body mass and reproductive attributes in 2 aphidophagous ladybirds, Menochilus sexmaculatus （Fabricius） and Propylea dissecta （Mulsant） was examined on Aphis craccivora Koch at 27 4- 1 ~C temperature. A clear bimodal （2 peaks, where the first peak represented the fast developing and the 2nd peak slow developing individuals） pattern of distribution at each photoperiod was found. The proportion of slow and fast developing individuals in a cohort differed with photoperiods. The slow developing individuals were more in numbers at 8L ： 16D, in equal numbers at 14L ： 10D and in less numbers at 16L： 8D, indicating that the variation in emergence was owing to exogenous cues influenced differential rates of mortality. Slow developing individuals had female biased sex ratio, higher longevity and lower body mass than fast developing individuals. Fast developing females laid higher numbers of eggs with higher egg viability than slow developing females. Study of such variations in development at different photoperiods is helpful to understand its role in the development of insects particularly ladybirds and permits the selection of fast developing bioagents for their use in biocontrol of pest species.展开更多
