| 1 | 流域水文模型中的土壤质地转换与饱和导水率Ks值确定显示文摘构建于GIS基础之上的分布式水文模型,近年来得到了普遍的应用和较快的发展。土壤质地数据是模型构建的重要参数,但实际运用中,常存在土壤数据多种统计口径并存、与模型运算所需的数据类型不一致等问题,限制了模型的应用和模拟的精度。根据土壤典型剖面值,利用3次样条函数曲线插值得出了模型所需土壤粒径分布。根据粒径组成,使用NeroTheta软件计算出饱和导水率Ks值。为构建分布式水文模型数据库,确定主要土壤参数提供了简便有效的方法。 | 陆颖 Sam BUCHANAN 何大明 | 2008 | 云南地理环境研究2008，20，5： | 5 |
| 2 | Ecological Footprint Dynamics of Yunnan, China显示文摘A fundamental element of sustainable development is that humans live within nature's biological capacity. Quantifying this, however, remains a significant challenge for which there are many emerging tools. The concept of the Ecological Footprint is one such accounting tool for comprehensive assessment of the status of sustainable development, based on integration of resource consumption and land capacity, reflecting the human impact on the environment. A region's development is defined as unsustainable when the Ecological Footprint surpasses the biological capacity. In this paper, the Ecological Footprint concept was applied in assessing the development of Yunnan Province, China in a period between 1988 and 2006. The results showed that the Ecological Footprint per capita in Yunnan rose from 0.854 gha in 1988 to 2.11 gha in 2006. Ecological deficit, defined as when the human demand on the land surpasses the regions biological productive capacity, emerged in 1991 and quickly increased from 0.02 gha in 1991 to 1.05 gha in 2006. The increase in the ecological deficit is primarily a result of the rapid increase in population and consumption level. To achieve sustainable development in Yunnan, production and consumption rates need to be modified. | LU Ying HE Daming Sam Buchanan LIU Jiang | 2009 | Journal of Mountain Science2009，6，3： | 2 |

| 4 | 为初级保健中的母乳喂养妇女提供有效的循证支持显示文摘婴儿凯尔是其母亲的第一胎,在足月时通过剖腹产平安出生,他出生体重为3.550 kg,现在已2周,却和他出生时一样重。他的母亲艾莉联系了诊所,预约了全科医生,并参加了一个视频咨询。艾莉正在母乳喂养凯尔。她解释说,由于疫情,她感觉很难获得母乳喂养支持。她诉说了喂母乳时的疼痛,并解释说在喂食后凯尔仍会一直哭闹和焦躁不安,担心凯尔摄入的母乳不足。在网上搜索相关信息后,艾莉猜想凯尔是否对乳蛋白过敏,并向医生咨询是否应该把乳制品排除在她的饮食之外。她泪流满面,感到情绪低落和孤立无援。 | Joyce Marshall Sam Ross Phyll Buchanan Anna Gavine 梁婷(译) | 2022 | 英国医学杂志中文版2022，25，5： | 0 |
