地面水环境在缩小天津原属海退之地,在距今10000年时,除北部蓟县山区外,其余地区均被海水淹没。到距今7000年以来,一方面因黄河等泥沙的沉积,另一方面海水逐渐东退,形成的滨海平原不断扩大,不同时代的古海岸带明显地反映在天津特有的贝壳堤上。那时由于河、海的不等量沉积形成的低洼湖沼,比比皆是,一片水的环境,雨季一到皆为泽国; 相似文献

《Journal Of Human Behavior In The Social Environment》2013,23(3):25-59
SUMMARY This paper presents a conceptual framework for selecting and organizing concepts of the social environment. It expands upon the traditional Human Behavior and the Social Environment perspectives used in social work curricula in the United States by identifying how a macro-systemconsisting of the intersection of four societal forces (social justice, social problems, social policy, and the political economy) works to influence a micro-systemof community, organizational, and group dynamics. In this framework, the impact of the macrosystem is mediated by collective responses of partnerships, alliances, and networks convened to address these forces. The framework is useful for understanding the complexity and uncertainty of the social environment in modern society with specific reference to: (1) how macro-system forces work to shape a constellation of community and organizational concerns, (2) how collective responses that seek solutions can be understood as instruments for achieving meaningful social change, and (3) how micro-systems concepts of structure (stages of development, systems of exchange, and diversity) and process (power and leadership, conflict and change, and integrating mechanisms) can inform practice. 相似文献

Andrew Hargrove 《Sociological inquiry》2023,93(2):341-369
The world is currently confronting two water crises, a developmental crisis concerning populations who lack access to water and an environmental crisis regarding water scarcity and freshwater resource depletion. Are we as academics addressing the complexity of these issues? Using network analysis of over 5,000 articles that address water development and water scarcity, I generate a co-citation network to identify the overlap between development and environmental water literatures in academic journals. The results suggest that the development literature only has a 6.28 percent overlap with the environmental literature and the environmental literature has a mere 1.92 percent overlap. Overall, this research suggests that there is an extreme lack of academic articles that address water scarcity and water development concurrently. Until we as an academic community become more nuanced in our studies of water, we will lack a full understanding of how to solve these seemingly contradictory problems. I conclude by drawing on critical Marxist and “Frankfurt School” perspectives to explain this apparent disconnect. 相似文献
