Variations in carbon isotopic ratios (δ 13.) of C3.plants and distribution of C4 plants were investigated along an altitudinal transect on the eastern slope of Mount Gongga, and the {2. effects on them were discussed. It is shown that plants with C4 photosynthetic pathway mainly occur at altitudes below 2.00 m a.s.l., suggesting that the low summer temperature is responsible for the distributional pattern. In addition, δ 13. of C3.plants increases with elevation at the region above 2.00 m a.s.l. with the characteristics of humid climate, and the increase rate in δ 13. for C3.plants is about 1.3. per kilometer. Temperature determines the altitudinal trend of δ 13..

Dong ethnic people have rich indigenous knowledge in terms of their daily life and production, which plays an important role in the sustainable development of their village. This paper aims to understand traditional knowledge of Dong ethnic people in resource management and population control, including traditional resource management, traditional medicinal knowledge and village regulations in Zhanli Village in Southeast Guizhou Province. The research methods include key informant interview, group discussion, participant observation and secondary data collect- ing. The results show that Zhanli villagers try their best to utilize indigenous knowledge to manage the natural resources and keep the stable population to make themselves live in a sustainable way. Indigenous knowledge plays an important role in managing their limited natural resources and keeping the population stable under an excellent condition. Zhanli villagers employ indigenous knowledge to manage natural resources and use local herbs to control the population. Village regulation terms significantly influence villagers’ awareness in resource management and birth control. Women play the chief role in employing indigenous knowledge in weaving as well as medicinal knowledge in birth control, and these kinds of knowledge are passed down through the female line. However, the inheritance style of traditional knowledge is decreasing. Indig- enous knowledge plays an important role in the sustainable development of this village, which gives implications for development practices to involve indigenous knowledge to achieve sustainable development.

Land use changes are regarded as landscape pattern change driven by many interactive natural and social-economic factors. Different combination of physical geographical elements induced the difference of spatio-temporal pattern of land use change. There are four physical geographical regions in Mongolian Autonomou County of Qian Gorlos of Jilin Province. Based on spatial analysis and statistical analysis, we conclude that the primary pattern of land use and the tendency of land use changes are all different in four physical geographical regions. During 1987 – 1996, the dominant land use change processes were from grassland or forest to arableland, from unused land to paddy and grassland to unused land. Though land use change is mainly affected by social and economic condition in short period, the composite characters of physical geographical elements controls land use dynamic process. The relationship between land use dynamic process and the character of physical geographical units differ in different regions. Possible human impacts on land use change are explored with application of buffer areas of series distance along main roads and radius around main settlements. A few models are built to describe the relationship between land use spatial change rates and distance to road and settlements. According to our result, the relationship with the proximity to roads was a negative liner function, with the change rate decreasing rapidly when moving away from roads. Within a distance of less 7.5km from main traffic lines, land use changes occur red more. The bulk of grassland was apt to be opened up for cultivation around the settlements and the transformation from dryland to paddy occurred within the distance of 1km away from settlements.

唐山滨海湿地资源丰富,类型多样,天然湿地和人工湿地交错分布。湿地的空间形态基本按照等高线与海岸线呈近似平行的带状分布,其形成受控于研究区活跃的新构造运动所造成的地面快速沉降以及地表水系的分布与改变,也明显受到降水量、蒸发量及其季节和年际变化等气候条件的制约,还受到沉积环境、地层结构、地下水赋存条件等自然因素的影响。然而,伴随近年来研究区大规模的工农业建设和城市化进程,人为因素上升为滨海湿地机能退化的主控因素。城市化、工农业现代化和港口建设等人类活动以及由此引发的环境污染,造成湿地面积萎缩和生态机能的减退,已经明显超过了自然因素对滨海湿地演化的影响。唐山滨海湿地的形成和发育是对研究区构造运动—气候演化—环境变迁之间耦合关系的响应记录,更是现代工农业生产活动的结果。

采用田间小区试验,设置不施锌、土施硫酸锌、喷施硫酸锌、土喷结合硫酸锌以及土施纳米氧化锌、喷施纳米氧化锌和土喷结合纳米氧化锌7个处理,研究了不同锌肥施用方式对小麦产量、锌等微量元素含量和累积量以及锌利用率的影响。结果表明,各施锌处理对小麦籽粒产量均没有显著影响,而施用纳米氧化锌则显著增加籽粒锌含量,单独土施使锌含量从对照的18.9 mg·kg^(-1)增加至2..6 mg·kg^(-1),增幅达3.%;单独喷施籽粒锌含量增加至2..4 mg·kg^(-1),增幅达50%;土喷结合处理籽粒锌含量增加至3..2.mg·kg^(-1),增幅达60%。单独喷施纳米氧化锌处理较硫酸锌处理提高籽粒锌强化指数近3.,达到9.7 mg·kg^(-1);籽粒铁含量较喷施硫酸锌提高近2.5倍,达到58.9mg·kg^(-1)。同时,单独喷施纳米氧化锌显著增加了叶片锌累积量,使得地上部锌利用率达到3.%,较硫酸锌处理增加近4倍,差异达到显著水平。由此可见,喷施纳米氧化锌较硫酸锌对提高小麦籽粒锌铁含量有更好的效果,可能由于纳米颗粒的小尺寸效应降低了叶片上锌的脱落。

茶叶是我国特色地标性农产品之一,具有深厚的文化底蕴和区域资源优势,其产地溯源与品质鉴别具有重要意义。本文系统介绍了多矿质元素、稀土元素、稳定同位素等地球化学手段在国内外茶叶产地溯源和品质鉴别中的研究进展,并分析了这些方法的优势和不足。今后的相关研究应该进一步明确元素及同位素在"土壤-茶鲜叶-成品茶"中的迁移转化规律,辨识多因素如加工方式、人类活动及污染物等在茶叶"种植-生长-加工"过程中对其原产地信息及品质的影响,结合传统鉴别技术及大数据方法并综合比较多种统计模型,以期系统地建立和完善主要茶产地及名优茶产品的元素-同位素指纹图谱。这对茶树生长和生态环境改良及优势品种的选择,保护名优茶产品优势,树立正确的产品意识,建立良好的贸易秩序具有深远的意义。
