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.

中国东部主要河流河水腐殖酸的起源、含量及地域分异规律

测定了中国东部地区主要河流河水、悬浮物和沉积物中腐殖酸含量,研究了该地区河水腐殖酸含量的地域分异规律,并探讨了河水腐殖酸的可能来源。结果表明,所研究河流河水腐殖酸含量在0.9—14.4mg/L范围内,中值为4.16mg/L,并有北高南低的一般趋势。黑龙江上游及松花江北部支流的河水腐殖酸含量在8.5mg/L以上,滦河以北其它地区在3.9—6.4mg/L范围内,黄河以南区域则在0.9—3.3mg/L之间,所研究地区河水中的腐殖酸为混合起源的,它既来自河流悬浮物和沉积物中腐殖酸的释放,又来自流域表土中腐殖酸的淋溶。     

Effects of fluoride on growth and reproduction of the army worm, Mythimna separata (Walker)

This paper deals with effects of airborne fluorine on the army worm, Mythimna separata (Walker), by rearing the larvae on the wheat foliage exposed to HF or fumigating the larvae on the artificial diet with the pollutant. Larval relative growth rate (GR) and index of population trend of the insect reduced by 5% and 11%, respectively, when the larvae were reared on the foliage taken from the wheat plants exposed to 0.87 g·dm-2·day-1 of fluorine compared with those of the control. An extra instar appeared in a majority of the larvae treated. Survival rate and GR of the larvae on the wheat plant being exposure to the same concentration of fluorine in field open-top fumigation device were 40% and 15% lower than that of the control, respectively. Similar experiment with the insect on the artificial diet also showed that direct impact of the pollutant on the army worm was greater than its indirect effect via their host plant.
