近几年来,以《有关做好"十一五"阶段环境宣传教育工作规划》为主要方针,国内各省区环保部门、宣传教育部门在积极开展本地区环境宣传教育工作的同时,积极动员社会各行各业人士参与到当中,截至目前已取得明显成效。现阶段,该工作对于增强各行各业领导以及公众的环保意识、生态文明环境的建设推进、环境保护发挥了积极的影响作用。当前由于国内环境污染情况加剧,就为环境保护工作增添了不小的难度。对于此,为切实做好新时期国内环境教育宣传活动,要求全社会内形成自觉环境保护的意识,并在与生态文明建设推进力量的结合之下,积极推进生态文明建设和环境友好型社会的建设。本文将据此提出系列建议和论述,希望可为相关领域从业人员提供一些指导建议。 相似文献

在国内食品安全和环境保护双重压力下,国内养猪业发展生态健康养殖模式是必然趋势。"猪-沼-构树-猪"生态养殖模式是以沼气处理工程为纽带,把猪场粪污变废为有机肥,用于种植构树;反过来构树叶生物发酵处理为饲料,用于养猪生产的一种新兴生态循环养殖模式。该模式推广应用可以消纳猪场粪污,提供可再生性清洁能源,推进农村"以气代煤"的进程,改善农田土壤,优化环境,降低养猪成本,是经济效益、社会效益和生态效益有机统一的生态循环健康养殖发展模式。 相似文献

Two different conditioning procedures, one appetitive and the other aversive, were used in separate attempts to demonstrate response to magnetic fields in the goldfish, Carassius auratus. Our results lead us to question those of an orientation experiment by Becker, although we recognize the possibility that goldfish may be sensitive primarily to magnetic field direction rather than intensity and that their directional sensitivity may be evidenced most readily by orientation in the field. 相似文献

Croppers to livestock keepers: livelihood transitions to 2050 in Africa due to climate change 总被引:1,自引:0,他引:1
The impacts of climate change are expected to be generally detrimental for agriculture in many parts of Africa. Overall, warming and drying may reduce crop yields by 10–20% to 2050, but there are places where losses are likely to be much more severe. Increasing frequencies of heat stress, drought and flooding events will result in yet further deleterious effects on crop and livestock productivity. There will be places in the coming decades where the livelihood strategies of rural people may need to change, to preserve food security and provide income-generating options. These are likely to include areas of Africa that are already marginal for crop production; as these become increasingly marginal, then livestock may provide an alternative to cropping. We carried out some analysis to identify areas in sub-Saharan Africa where such transitions might occur. For the currently cropped areas (which already include the highland areas where cropping intensity may increase in the future), we estimated probabilities of failed seasons for current climate conditions, and compared these with estimates obtained for future climate conditions in 2050, using downscaled climate model output for a higher and a lower greenhouse-gas emission scenario. Transition zones can be identified where the increased probabilities of failed seasons may induce shifts from cropping to increased dependence on livestock. These zones are characterised in terms of existing agricultural system, current livestock densities, and levels of poverty. The analysis provides further evidence that climate change impacts in the marginal cropping lands may be severe, where poverty rates are already high. Results also suggest that those likely to be more affected are already more poor, on average. We discuss the implications of these results in a research-for-development targeting context that is likely to see the poor disproportionately and negatively affected by climate change. 相似文献

密西西比河是美国第一大河。它一路曲曲弯弯向着墨西哥湾蜿蜒流去.沿途形成广袤的洪泛平原,滋润着美国大陆41%的土地。水量也比美国其他河流都要多。密西西比河及其洪泛平原哺育着400多种野生动植物。北美地区40%的水禽都沿着密西西比河的路径迁徙。密西西比河对于美国。如同长江对于中国,无论从经济还是生物多样性保护等方面,其作用都是举足轻重。 相似文献

Adoption of glyphosate-resistant canola (Brassica napus L.) has increased glyphosate applications to this crop, and concerns have been raised about unintended consequences of these multiple applications. A field trial was conducted to evaluate the effects of pre-seed and in-crop glyphosate and alternative herbicides on soil microbial community functional structure, diversity and biomass. Pre-seed treatments were 2,4-D, glyphosate and 2,4-D + glyphosate, and in-crop treatments were glyphosate applied once, glyphosate applied twice, ethalfluralin, ethalfluralin + sethoxydim + ethametsulfuron + clopyralid, and sethoxydim + ethametsulfuron. Rhizosphere and bulk soil was collected at flowering stage of canola and analyzed for bacterial community-level substrate utilization patterns and microbial biomass C (MBC). Where differences were significant, pre-seed application of both 2,4-D and glyphosate altered the functional structure and reduced the functional diversity of soil bacteria, but increased MBC. These effects were not necessarily concurrent. The reduction in functional diversity was due to reduction in evenness, which means that the soil where both pre-seed herbicides had been applied was dominated by only few functional groups. In 1 year, two in-crop applications of glyphosate also reduced the functional diversity of soil bacteria when applied after pre-seed 2,4-D, as did in-crop sethoxydim + ethametsulfuron following pre-seed glyphosate. Even though significant differences between herbicides were fewer than non-significant differences, i.e., there were no changes in soil microbial community structure, diversity or biomass in response to glyphosate or alternative herbicides applied to glyphosate-resistant canola in most cases, the observed changes in soil microbial communities could affect soil food webs and biological processes. 相似文献
