Analysis on sensitivit and landscape ecological spatial structure of site resources

This article establishes a set of indicators and standards for landscape ecological sensitivity analysis of site resources by using the theories and approaches of landscape ecology.It uses landscape diversity index(H),evenness(E),natural degree(N),contrast degree(C) to study spatial structure and landscape heterogeneity of site resources and thus provides a qualitative-quantitative evaluation method for land planning and management of small ,medium scale areas.The analysis of Yantian District,Shenzhen of China showed that Wutong Mountain belonged to high lanscape ecological sensitivity area,Sanzhoutian Reservoir and Shangping Reservoir were medium landscape sensitivity area and high ecological sensitivity area;Dameisha and Xiaomeisha belonged to medium sensitivity area caused by the decline of natural ecological areas.Shatoujiao,Yantian Pier belonged to low sensitivity area but urban landscape ecological development had reshaped and influenced their landscape ecological roles in a great extent.Suggestions on planning,protection goals an development intensity of each site or district were raised.

Biogenic VOCs emission inventory development of temperate grassland vegetation in Xilin River basin, Inner Mongolia, China

Given the key role of biogenic volatile organic compounds(VOCs) to tropospheric chemistry and regional air quality, it is important to generate accurateVOCs emission inventories. However, only a less fraction of plant species, in temperate grassland of Inner Mongolia, has been characterized by quantitative measurements. A taxonomic methodology, which assigns VOCs measurements to unmeasured species, is an applicable and inexpensive alternation for extensive VOCs emission survey, although data are needed for additional plant families and genera to further validate the taxonomic approach in grassland vegetation. In this experiment, VOCs emission rates of 178 plant species were measured with a portable photoionization detector( PID). The results showed the most of genera and some families have consistent feature of their VOCs emission, especially for isoprene, and provide the basic premise of taxonomic methodology to develop VOCs emission inventories for temperate grassland. Then, the taxonomic methodology was introduced into assigning emission rate to other 96 species, which no measured emission rates available here. A systematical emission inventory of temperate grassland vegetation in Inner Mongolia was provided and further evidence that taxonomy relationship can serve as a useful guide for generalizing the emissions behavior of many, but not all, plant families and genera to grassland vegetation.     

祁连—柴达木盆地北缘地区石炭系泥岩沉积地球化学特征

详细研究了祁连—柴达木盆地北缘地区石炭系泥岩的微量元素和稀土元素地球化学特征。各微量元素在各剖面及不同层位变化相当复杂 ,但仍有一定规律 ,这种变化与其物源供应和沉积成岩环境有关。各样品稀土总量变化较大 ,以甘肃永昌煤山子剖面总量最高 ;各泥岩样品轻稀土富集 ,Eu负异常 ,δEu介于 0 .4 4～0 .90之间。微量、稀土元素组合及比值的变化 ,显示物源区母岩为花岗岩和玄武岩的混合 ,稀土分布模式显示源岩为粘土岩、花岗岩和中性岩的混合 ,两者示物源一致。元素的丰度及其比值 ,反映当时水介质环境大部分为海相 ,亦有部分为陆相 ,与其它相标志所表征的结果是一致的。
