简介：本文旨在剖析影响土地荒漠化发生发展的更深层次的内在的社会经济因素，以及中国治理荒漠化的速度及规模．作者从１１个方面分析了这一问题，其中人口问题、传统习惯、实际问题和认识问题是引起土地荒漠化的根本原因；利益驱动行为、政策、宣传失误、法律、法规不健全和组织领导等主观原因，虽然是很重要的，但如严肃对待较易解决．经济水平、科学技术及资金投入虽然也重要，但在目前防治荒漠化过程中并不是根本的限制因子，在短时期内难以彻底解决，而必须在实践中逐步加以解决．

简介：在最近的年里，在改变沉积产量的人的活动的角色在上面的长江为水力的工程和水保存设计的构造变得更明显，但是它没在宏规模被评估。作为一个例子拿四川省和重庆城市，这份报纸在1989和2007基于节数据在上面的长江学习在社会经济的因素和沉积产量之间的关系。结果证明沉积产量显著地与人口密度被相关并且栽培了区域，前者与沉积产量有关更仔细在看起来是。而且在沉积产量对人口密度的关系，人口密度的批评价值存在，在哪个下面沉积收益随人口密度并且在沉积收益与人口密度的减少在哪个上增加上的增加增加。现象实质上反映自然因素的影响，例如沉积产量上的地形学，降水和土壤性质，和一些人的活动。有更高的人口密度的区域比批评价值位于学习区域的东方并且被平原，山和低山描绘，而反面位于西方并且由中间、高的山描绘了。在东方区域，更多的人与地区性的土壤侵蚀是细微的一个低斜坡在陆地上住在一起；因此，沉积产量否定地与人口密度被联系。在西方的区域，相反，人口与通常导致自然侵蚀的更高的紧张的丰富的土壤和水资源在区域趋于到总数，并且接着，在这些区域的高紧张的农业惯例可以进一步加强本地土壤侵蚀。人口趋于与更舒适的环境和更少的沉积产量与坏环境和高沉积产量从区域搬到区域，这也被发现。自然因素比东方区域的在西方的区域的沉积产量上有更大的影响。通常，自然因素在上面的长江在沉积产量上起一个主导的作用。

简介：AbstractBackground:Cardiovascular disease (CVD) is the major noncommunicable disease (NCD) accounting for 17.9 million deaths. If current trends continue, the annual number of deaths from CVD will rise to 22.2 million by 2030. The United Nations General Assembly adopted a sustainable development goal (SDG) by 2030 to reduce NCD mortality by one-third. The purpose of this study was to analyze the CVD mortality trends in different countries implementing World Health Organization (WHO) NCD Action Plan and emphasize effective ways to achieve SDG.Methods:WHO statistics, based on the Member-States unified mortality and causes-of-death reports were used for analyzing trends and different interventions.Results:Reduction of CVD mortality from 2000 to 2016 in 49 countries was achieved for stroke at 43% and ischemic heart disease at 30%. Smoking prevalence and raised blood pressure (RBP) decreased in 84% and 55% of the countries. Eighty-nine percent of high-income countries (HIC) demonstrated a decline in tobacco smoking against 67% in middle-income countries (MIC). Sixty-nine percent of HIC demonstrated a decline in RBP against 15% in MIC. CVD management, tobacco, and unhealthy diet reduction measures are significantly better in HIC. The air pollution level was higher in MIC.Conclusion:Building partnerships between countries could enhance their efforts for CVD prevention and successful achievement of SDG.
