关于“环境污染对生态平衡影响”的检索报告一、课题分析环境污染是指人类直接或间接地向环境排放超过其自净能力的物质或能量，从而使环境的质量降低，对人类的生存与发展、生态系统和财产造成不利影响的现象。
具体包括：水污染、大气污染、噪声污染、放射性污染等。
环境污染的产生是一个从量变到质变的过程，目前环境污染产生的原因主要是资源的浪费和不合理的使用，使有用的资源变为废物进入环境而造成危害。
随着世界经济技术的发展和人民生活水平的提高，世界范围内的环境污染也越来越严重，其中包括发达国家，也包括发展中国家。
环境污染会给生态系统造成直接的破坏和影响，如沙漠化、森林破坏；同时，环境污染也会给生态系统造成间接的危害，有时这种间接的环境效应的危害比当时造成的直接危害更大，也更难消除，例如温室效应、酸雨、臭氧层的破坏给人类造成了挥之不去的巨大影响。
因此，如何保护生态平衡，防止环境污染扩散已经成为不可不谈的话题，对环境污染对生态平衡影响的研究是非常有必要的。

三、检索方法与检索步骤检索方法：初级检索检索步骤如下：1、2、四、检索结果检索结果如下：1、《Factors influencing local ecological knowledge maintenance in Mediterranean watersheds: Insights for environmental policies》内容如下：Local ecological knowledge (LEK) has been found to be one of the main bridges to manage biocultural diversity. We analyzed the factorsaffecting LEK maintenance and transmission in a Mediterranean watershed. We used a mixed methods approach to evaluate the agricultural LEK in three different dimensions: biological, soil and water management, and forecasting. We found that the main factors for its maintenance were the respondent's time living in the area and the social relationships established among farmers, which involved partner collaboration and farmer information exchanges. Protected areas also played a key role for maintaining the LEK associated with soil and water management. Finally, we found that outmigration and mechanization were the most important indirect drivers of change underlying LEK erosion. We suggest that environmental policies should focus on promoting this experiential knowledge, considering both intergenerational renewal and the gendered aspects of this knowledge.2、《Longitudinal- and transverse-scale environmental influences on riparian vegetation across multiple levels of ecological organization》内容如下：Riparian vegetation is distinct from adjacent upland terrestrial vegetation and its distribution is affected by various environmental controls operating at the longitudinal scale (along the river) or transverse scale (perpendicular to the river). Although several studies have shown how the relative importance of transverse or longitudinal influences varies with the scale of observation, few have examined how the influences of the two scales vary with the level of ecological organization. We modeled vegetation-environment relationships at three hierarchically nested levels of ecological organization: species, plant community, and vegetation type. Our hierarchically structured analyses differentiated the spatial extent of riparian zones from adjacent upland vegetation, the distribution of plant community types within the riparian zone, and the distribution of plant species within community types. Longitudinal gradients associated with climate and elevation exerted stronger effects at the species level than at the community level. Transverse gradients related to lateral surface water flux and groundwater availability distinguished riparian and upland vegetation types, although longitudinal gradients of variation better predicted species composition within either riparian or upland communities. We concur with other studies of riparian landscape ecology that the relative predictive power of environmental controls for modeling patterns of biodiversity is confounded with the spatial extent of the study area and sampling scheme. A hierarchical approach to spatial modeling of vegetation-environment relationships will yield substantial insights on riparian landscape patterns.3、《A Case Study on the Influence of Regional Ecological Environment based on Fishing Woman Dress in Xun Pu Village》内容如下：Taking fisher-woman dress in the coastal environment as an example, to analyze the effect of the natural ecological environment on dress, the functional effect of Marine natural environment on headwear and dress, the effect of the environment on clothing material and color, and the effect of humanistic ecological environment on clothing decoration and accessories under the background of Marine culture. it is concluded that regional dress features, from the structure to the color, occurred, developed and evolved in a particular ecological environment. It has close relationship with the environment the difference of the natural environment is one of the important factors of diversification of clothing design. It comes from nature, and also beautify the natural. This is the charm of Oriental clothing art and the clothing art beauty important features.五、文献综述（关于检索论文的内容）笔者阅读了大概30多篇文献，其中既有国内的文献，又有国外的文献。
