Study on the effect of highway construction on photosynthetic rate of roadsides plant in Longitudinal Range-Gorge Region

A case study was conducted on Dabao （from Dali city to Baoshan city） and Sixiao （from Simao city to Xiaomengyang town） highways in Longitudinal Range-Gorge Region to investigate the effect of highway construction on photosynthetic rate of roadsides plants. The dominant species in the plant communities were selected to measure the variation of their photosynthetic rate with the distance to the highway, so as to analyze the effect of highway construction on photosynthesis and growth of roadside plants by using mathematic methods including contrast analysis, regress analysis and so on. Results indicate： （1） Highway construction reduced the plant photosynthetic rate of the arbor and crop, and improved the plant photosynthetic rate of the shrub and herbage; （2） highway construction directly affected the plant photosynthetic rate through changing the structure of plant community and living state of plant, and indirectly affected the plant photosynthetic rate through changing its environmental factors; （3） the location and topography of road are also important factors affecting plant photosynthetic rate on roadsides, the influencing incidence and intensity on plant photosynthetic rate under different topographies caused by the two selected highways were obviously different.

子洲地区山西组及盒8段有利砂体成因探讨

目的为了查明鄂尔多斯盆地东部子洲地区山西组及盒8段有利砂体的特征及成因,进而寻找有利砂体及高产天然气聚集区。方法采用野外观察与室内研究相结合的方法。结果大量的砂岩样品统计显示,山西组砂岩类型以岩屑砂岩、石英砂岩为主,其次为岩屑石英砂岩,盒8段砂岩主要为岩屑砂岩、岩屑石英砂岩;不同类型的砂岩物性不同,石英砂岩物性最好,其次是岩屑石英砂岩,岩屑砂岩物性最差;沉积相分析认为,子洲地区山西组主要为三角洲前缘,盒8段发育辫状河三角洲前缘,探明了重点气层组山23及盒82沉积微相的平面展布。结论有利的天然气储集体主要形成于水下分流河道微相,由于山西组和盒8段形成时古地理条件的不同,其砂体类型及储集性能也有一定的差异。     

Muhaka icipe,an enigmatic new genus and species of Kleidotomini (Hymenoptera: Figitidae: Eucoilinae) from an East African coastal forest

A remarkable new eucoiline genus and species, Muhaka icipe, is described herein. The genus is clearly a Kleidotomini, but is distinguished from other genera in the tribe by a unique head and scutellar morphology. The genus belongs to the ‘wedge-head’-syndrome group of species that, to date, is unique to Afrotropical eucoilines. The new genus and species is reminiscent of Stentorceps Quinlan and Nanocthulhu Buffington, but is readily distinguished from these genera. Muhaka was collected from a threatened kaya (sacred forest) of coastal Kenya. The biological importance of this and other kaya forests, as well as their protection, is discussed.
