上海,传统的工商业城市,中国的经济中心.新中国成立之后特别是改革开放以来,经济总量和增长速度持续较快发展,但现实支撑却是地少人多、自然资源贫乏、环境容量有限.随着上海城市化、工业化进程的加快,资源、环境与经济发展的矛盾对上海的可持续发展提出了严峻挑战,在新的历史和现实背景下,上海市如何实现华丽转身?如何走出一条产业转型、资源高效利用、环境友好的绿色发展之路?环境保护该如何发挥出正能量? 相似文献

马克思的历史使命是为了人类的解放。从理论高度看,马克思以"现实的个人"为出发点,构建了历史唯物主义的理论框架,又以"现实的个人"为落脚点,揭示了人民群众是历史的真正创造者,是实现历史使命的主体力量。从实践角度看,马克思的历史使命是对贫苦大众艰辛生活的积极回应,是资本双重逻辑不断演化冲突的必然结果,是植根于无产阶级及其政党的革命运动。从价值维度看,马克思的历史使命以"现实的个人"、每个人的自由发展、自由个性、人与自然的和谐相处等思想为科学内涵,生动反映出人自身、人与人、人与社会、人与自然的和谐理念。因此,从理论高度、实践角度、价值维度解读马克思的历史使命,这对于中国共产党的初心和使命的实现有着重要启示。 相似文献

The results of studies on dust aerosol optical properties obtained during the U.S.S.R.-U.S. experiment are discussed. The ground-based and aircraft measurements carried out during the experiment allow the estimation of characteristic values of aerosol optical depth, aerosol light-scattering coefficients, the degree of linear polarization, and aureole phase functions for different atmospheric conditions in Central Soviet Asia. Two dust storms were observed for which the recorded aerosol optical depth at λ = 0.55 μm {τa(0.55)} reached 1.5 on 16 and 17 September 1989, and 3.5 on 20 and 21 September 1989. The optical characteristics (spectral dependence of the optical depth, degree of linear polarization) were similar for two dust episodes. 相似文献

From a total of 490 cystic fibrosis (CF) high-risk families under supervision (mostly Russian Slavs from the European part of the country), DNA data including both direct screening for some CF gene(CFTR)mutations(deIF508, G551D and 1677delTA) and allelic polymorphism studies with tightly CF linked DNA markers were collected from 261 families. All full families (129) and 86 CF families with a deceased index child were found to be either fully (42 per cent) or partially (40 per cent) informative for DNA analysis. Prenatal diagnosis (PD) was carried out in 161 CF families. Microvillar enzyme (MVE) assay was applied to all 140 PD at the second trimester either as a single test (88) or in conjunction with DNA analysis (52). The frequency of false-negative results of the MVE assay was 1.3 percent and that of false-positive results, as judged by the albumin meconium test, was 5.0 per cent. Ambiguous results of MVE analysis were found in 30 cases, 12 of which were verified by DNA analysis. Molecular diagnosis of CF at the first trimester was carried out in 21 cases and four pregnancies were terminated. Altogether, 39 pregnancies with a predicted high risk of CF fetuses were terminated. The low average frequency of delF508 in CF chromosomes of Russian Slavs (50 per cent), its remarkable inter-population variation, and the significant proportion of at-risk families without an affected child determine the necessity of combined molecular and biochemical (MVE assay) approaches for efficient prenatal diagnosis of CF in the former U.S.S.R. 相似文献
