利用能值分析方法对2011年民勤绿洲18个乡镇农田生态系统的环境资源条件、投入产出结构和可持续性进行了系统分析,构建了反映民勤绿洲农田生态系统综合水平的能值指标体系,运用主成分分析方法对其进行了综合评价和排序。结果表明:民勤绿洲农田生态系统可持续性强的是夹河乡,其他乡镇农田生态系统为消费型生态经济系统,可持续性弱;民勤绿洲农田生态系统能值综合水平存在着明显的地域差异,呈现东北片高于西南片、绿洲边缘带高于中心带的地理分布特征;民勤绿洲农田生态系统总体上不具有可持续性,不协调发展型区域和极不协调发展型区域农田面积占民勤绿洲农田总面积的73.68%,强、中、弱协调发展型区域只占26.32%。因此,目前民勤绿洲农田生态系统面临的不可持续性应当引起相关部门的高度重视。

A survey was co.ducted to determine whether myco.oxins were present in the foods co.sumed by red-crowned cranes（Grus japonensis） in the Yancheng Biosphere Reserve, China. co.lected in the reserve＇s co.e, buffer, and experimental zones during overwintering periods of 2013 to 2015, a total of 113 food samples were analyzed for aflatoxin B1, deoxynivalenol, zearalenone, T-2 toxin, and ochratoxin A using high performance liquid chromatography（HPLC）. The co.tamination incidences vary among different zones and the myco.oxins levels of different food samples also presented disparity. Average myco.oxin co.centration from rice grain was greater than that from other food types. Among myco.oxin-positive samples, 59.3% were simultaneously co.taminated with more than one toxin. This study demonstrated for the first time that red-crowned cranes were exposed to myco.oxins in the Yancheng Biosphere Reserve and suggested that artificial wetlands co.ld not be co.sidered good habitats for the birds in this reserve, especially rice fields.

利用稳定碳同位素数据(δ13C)分析了南非克鲁格国家公园混食性黑斑羚(Aepyceros melampus)时间和空间尺度上的食性变化,验证了两个假说,即有蹄类食性变化是由生境中木本植物与草本植物的相对配比导致;降雨控制有蹄类生态。结果表明:黑斑羚的食性涵盖了精食者-粗食者采食谱系,且食性中木本与草本比例在不同月间、季节、年度和区域间存在很大变化。栖息于开放性热带稀树草原和草原中的黑斑羚通常采食比生境中更高比例的草本,但在时间尺度上并不恒定。在克鲁格北部的一个区域(Punda Maria) ,黑斑羚采食的草本比克鲁格国家公园中其它任何区域都多。与其它生境相比,在河边的黑斑羚采食草本数量更少,尤其是在食性空间变化更为明显的旱季。因此,我们的数据不支持有蹄类食性组成变化是由生境中木本与草本比例不同造成的假说,食性与降雨量间也无明显的关系。我们的结果支持草本中蛋白含量增加引起黑斑羚采食比例的增加这一模型。粪便中氮含量在时间和空间上的变化很小,揭示在可利用食物中,无论木本还是草本,黑斑羚进行选择采食以保证最好的食物质量。基于这些结果,我们认为更具体的食物选择和可利用性最适采食理论能够更好地解释这种生态学变化。

AIM- To examine histology- and tumor-location specific risk factors of gastric cancer （GC）.METHODS： This was subjects were 216 GC the period 2000-2002 non-cancer patients hospital. We obtained habits, and others by a a case-co.trol study. The study patients newly diagnosed during and 431 co.trols selected from matching in age, gender, and information on lifestyles, dietary ***： The subjects who were not eldest among his/her siblings were at a slightly elevated GC risk （OR 1.3; 95% CI 0.8-2.0）. Salting meals before tasting was related to an increased GC risk （OR 3.5; 95% CI 1.6- 7.3）. Frequent co.sumptions of fruits （OR 0.3; 95% CI 0.1-1.0） and vegetables （OR 0.3; 95% CI 0.1-1.0） were related to decreased GC risks. On the other hand, frying foods （OR 1.9; 95% CI 1.0-3.6） and co.king with co.l （OR 1.8; 95% CI 1.3-2.6） were related to increased GC risks. Neither Lauren＇s histological classification （intestinal and diffuse types） nor tumor location significantly affected those associations except birth order. The subjects who were not eldest among his/her siblings had an increased risk of GCs in the distal and middle thirds, and their ORs were 1.7 （95% CI 1.0-2.8） and 1.9 （95% CI 0.8-4.3）, respectively. The co.responding OR in the upper third stomach was 0.3 （95% CI 0.1-0.9）. The differences of those three ORs were statistically significant （P = 0.010）.co.CLUSION： The present study shows that birth order, salt intake, co.sumption of fruits and vegetables, the type of co.king, and cigarette smoking are related to GC risk. In histology and tumor-location specific analyses, non-eldest person among their siblings is related to an increased GC risk in the distal and middle thirds of the stomach, and is related to a decreased GC risk in the cardia.
