For a nature reserve with forest ecosystem, the mostimportant economic values are the indirect use values, which provide human beings and other livingthings with beneficial services through ecological processes and functions. In this case study, aquantifying framework to estimate the annual indirect use values of forest ecosystem has beenestablished in Yaoluoping National Nature Reserve based on alternative cost method and opportunitycost method. The ecological functions assessed in the study relate to six aspects: soil protection,water conservation, CO_2 fixation, nutrient cycling, pollutant decomposition and disease and pestcontrol. These ecological functions provide an economic value of 86.1xl0~6 yuan (RMB) per year(US$10.37xl0~6), which is 25 times higher than the opportunity cost for regular timber production.This study can contribute to the monetary assessment of indirect use values of forest biodiversityand to the conservation and sustainable use of nature reserves.展开更多

The pit viper’s the total length measured 836 mm with a dorsal ground color of yellowbrown, decorated by 56 dark-brown transverse bands. The 4thsupralabial squama of the new species is separated from subocular by two squamae, and the tip of tail is orange; this combination of characters distinguish it from other species of the genus Protobothrops. Based on the body proportions, number of squamae, body color pattern, and comparing the data of its life history with those of other species of Protobothrops, we herein describe it as a new species, belonging to the genus of Protobothrops.展开更多
