This paper presents an understanding of the relationship between the environmental awareness(EA) and contemporary society of china. The EA of three of the major groups of china.s society, namely intellectuals, government officials, and urban societies are characterized one by one. A number of factors of affecting the EA were investigated in details, the keys among which are the personal level of knowledge and morality, the social and economic development level, environmental codes, environment\|related professional and public regulations, different professional performances. Some policy proposals are finally provided for enhancing the EA of china.s society.

The segmentation of the social protection system in china.makes the system inequitable and *** in the public sector, particularly civil servants, are overprotected,while employees in the nonpublic sector,especially farmers and rural migrant workers,are underprotected. Segmented pension insurance system impedes labor mobility and increases administrative *** polices,such as implementation of the New Rural Cooperative Medical System,New Rural Old-age Insurance Scheme, as well as the polices to promote migrant workers to participate in social insurance programs for urban employees,help improve the equity of social protection. However,the competition between different local governments on increase in welfare and overburden of the local finance due to escalating social expenditures have affected the sustainability of social protection *** following measures need to be taken to solve such problems. First is to avoid using social insurance coverage as an indicator to evaluate the performance of government officials. Second,on the one hand, the social spending responsibilities of the central government need to increase,and on the other hand,public transfers to less development regions need to augment for enhancing social assistance and merit goods *** is to reduce and remove the segmentation of social protection system through integrating or combining various segments under the same insurance program.

在大国竞争加剧的背景下,“全球南方”作为一支相对独立的政治力量活跃在世界舞台上,在全球治理、地区冲突中发挥重要作用。俄乌冲突爆发以来,印度将“全球南方”纳入对外战略布局,助力其大国战略,抬升国际威望。在政策层面,印度通过争做“全球南方”领袖、充当“西方”与“全球南方”的桥梁以及拓展“微型多边主义”的多项战略举措加强与“全球南方”的联系,将“全球南方”视为维护战略自主和对冲中国的重要手段。同时也应看到,印度的“全球南方”外交攻势仍面临诸多挑战:印度“全球南方”领袖合法性问题、印度与西方国家的深层矛盾问题、印度“全球南方”领袖角色面临激烈外部竞争。作为“全球南方”的当然成员,中国坚定维护“全球南方”的共同利益。在当下复杂严峻的国际形势下,中国在外交实践中应更加注重把“全球南方”国家作为优先方向,不断深挖合作潜力,培育合作动力,谋求共同发展,在高质量共建“一带一路”征程中推动“全球南方”在国际舞台上发挥更大作用。

Yunnan is the most both biodiverse region in china. An existing project of People, Land Management and Environmental Change of United Nations University aims to document the status of agrodiversity as a basis for meeting local needs, using Xishuangbanna and Baoshan as case studies. Studies reveal that a rich agrodiversity at levels of crop species and varieties, plant species in agricultural fields and diversified ecosystems have been developed and conserved through agricultural systems by small farmers. social-economic influences on agrobiodiversity are quite complex, but land tenure, household income and farmer association have played an important role in management of agrodiversity.
