Ecological compensation mechanism for urban green land and its application in Shanghai,China

Urban green land compensation plays an important role in county development, ecological environment management and many other fields. The concept, methods and principles of urban green land are introduced in this paper. According to the pay fee method, the value and ecological function of various types of urban green land were analyzed. The cost-benefit analysis method (CBAM) was used to estimate different external diseconomy benefits caused by green land loss. The authors applied CBAM to estimate such benefits in the case of Shanghai, China, and calculated the actual compensation value for green land. Results indicated that in 2002, the compensation value for the green land of Shanghai was RMB 8.58 × 10⁵ Yuan/hm².

To enhance the reproduction of Phanerochaete chrysosporium by adding natural lixiviums in liquid medium

Great promotion to the reproduction of white rot fungus Phanerochaete chrysosporlum by adding natural lixiviums such as from wood, maize core and potato in liquid medium was found in this research. Incubated in the liquid medium contained 10 mg/L glucose as carbon source with natural lixiviums for three days, the production of myeelium pellet reaches more than 80 g/L, which is 5 times more than that of without natural lixiviums. Incubated in the liquid medium contained 5 mg/L glucose as carbon source with natural lixiviums for three days, the production of myeelium pellet can reach 69.5 g/L, while the production in the medium without natural lixiviums is very low. When the liquid medium contained 1-20 g/L glucose as carbon source, the production of myeelium pellet in 3 d can only reach 12.5 g/L to 14.5 g/L. The fungus in the medium with potato lixiviums are easily contaminated by other microorganisms and in the medium with maize core lixiviums are easily bulking, while in the medium with wood lixiviums are neither easily contaminated nor bulking. Medium with wood lixiviums can produce more pellet than other medium, endure contamination and keep better sedimentation capacity. So that, wood lixivium is borer additive to the culture of white rot fungi in liquid medium. Addition of the mixture of wood, maize core and potato lixiviums is of advantage to the productian of mycelium pellet. The difference of the production in the medium with different amount of wood lixiviums showed little in the first 3 d, while it esnanded after 3 d. Wood lixiviums stimulate the growth of P. chrysosporium instead of supply organies which fungi need.

银矿与莫霍面的关系——以浙闽和天山地区为例

银是我国的紧缺矿种,也是全世界最走俏的金属商品,世界各国都在积极寻找新的银矿床。陆相火山岩 次火山岩型银矿床是最重要的银矿工业类型,多产于大陆板块边缘陆相火山岩广泛分布地区。根据元素组合可将银矿床分为单银型、金银型、银铅锌型和铜银型等等。它们在空间分布上与莫霍面有一定关系。单银型矿床多产于莫霍面比较浅的地区,铜银型矿床一般分布在莫霍面相对比较深的地区,金银型矿床和银铅锌型矿床通常置于单银型 铜银型中间地区。金银型与银铅锌型相比,前者分布地区的莫霍面深度比后者可能相对浅一些。
