论广西土壤的垂直地带性分布规律

广西山地上壤的垂直分布既有华南山地土壤垂直分布的一般规律，又有广西独特的特点．既有明显的纬度地带性变化和相应的垂直地带性变化，也有经度变化的分布规律．在影响广西山地上壤垂直地带谱变异的纬度、地形和距海远近诸因素中，地形结构为最显著因素．

县域土地生态经济系统区划研究--以广西横县为例

土地生态经济系统是融自然、社会、经济于一体的复合系统．文章以位于桂东南的横县为研究区，对土地生态经济分区的原则和指标体系进行了探讨，采用GIS技术建立了包括自然生态、土地资源和社会经济等信息的土地生态经济系统的空间数据库，选择其中40项特征指标，运用SPSS软件对研究区的21个农业乡(镇)进行了聚类分析，据此将研究区划分为4类8个土地生态经济分区，在分析各土地生态经济分区的主要特点基础上，提出了土地资源可持续利用和生态建设方向的合理性建议。

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.     

壮语动词语法化探因

动词语法化是人类语言发展过程的一种普遍现象，但是手致其语法化的因素在不同的语言中并不完全相同。壮语动词语法化的主要因素是句子的分裂、与词义相结合的句法变化、语法意义的转移。     

Shenzhousia qilianshanensis gen. et sp. nov. (Protodonata, Meganeuridae), a giant dragonfly from the Upper Carboniferous of China

A new dragonfly of family Meganeuridae Shenzhousia qilianshanensis gen. et sp. nov., discovered from Ningxia Hui Autonomous Region in North China, is described in the present paper. It has an estimated wingspan of about 450?500 mm and may be the largest fossil insect in Late Carboniferous Namurian Stage discovered by far. The new species is referred to Meganeuridae because of the presence of the characteristic oblique vein between anterior branch of radius (RA) and posterior branch of radius (RP) near the base of RP2. It differs from other genera within the family in the following characteristics: Precostal area short and not extending to the midwing; posterior branch of subcostal vein short, merging into costal vein near the level of originating point of IR₂; RP forking earlier than anterior branch of media basally; RP_1＋2 and RP_3＋4 parallel and close to each other for a long distance, and then diverge gradually surpass midwing.
