保护区内的生物多样性保护与周边社区经济发展之间的矛盾冲突是一个世界性的问题。以白马雪山自然保护区为研究对象,针对保护区的建设面临着巨大的人口压力、相当落后的经济状况和对资源的强烈需求等问题,深入研究资源管理的产权状况,探讨目前存在的产权不合理性,并进一步提出了保护区社区共管产权建设的合理模式。 相似文献

The concentrations of 56 hydrocarbons from C2 to C12 were measured simultaneously in the southbound bore, the northbound bore
and the exhaust air shafts of the Hsuehshan tunnel near Yilan, Taiwan for 12 days during 2007 and 2008. A total of 60 integrated
air samples were collected using stainless steel canisters and analyzed using GC/FID and GC/MS. The five most abundant species in
all samples were ethylene, acetylene, isopentane, propylene and toluene. The exit/entrance ratios of total non-methane hydrocarbons
(NMHC) concentration were 7.8 and 4.8 for the southbound and northbound bores, respectively. Furthermore, the exhaust from the
vertical shafts affects air quality in the neighborhood. The most abundant species of emission rate (ER) was toluene (21.93–42.89
mg/sec), followed by isopentane, ethylene, propylene and 1-butene, with ER ranging from 2.50 to 9.31 mg/sec. The species in the
three exhaust air shafts showed that the reactivities of these emissions are similar to those of vehicle emissions. Notably, the control of
emissions in the vertical shafts of the vehicle tunnel will be important in the future. 相似文献
