基于新疆1995—2014年农业生产碳排放源,建立碳排放关系数据库。应用广义神经网络(generalized regression neural network,GRNN)构建了排放量预测模型,结合平均影响值(mean impact value,MIV)方法对碳排放影响因素进行量化。结果表明:1)GRNN模型预测碳排放的平均绝对百分误差和拟合优度分别为2.7860%和0.8720;2)新疆人口、人均GDP、农业贡献值、农机总动力和农户固定资产投资等因素对农业生产碳排放的影响程度分别为0.6210、0.2377、0.3698、0.8500和0.1000。该成果可为新疆碳排放总量分析和影响因素量化方面提供参考。 相似文献

Religion in its most ideal form is seen as a powerful force to create ecological transformations to succeeding generations
that share similar religious beliefs. This provides an interesting argument for enhancing their role in sustainability transitions.
Malaysia is a relevant geographical context in this regard since almost all of its citizens formally embrace some kind of
religious belief. However, such ideas are discussed mostly at the theoretical level with little systematic empirical investigation.
This paper aims to fill this gap by presenting theoretically informed empirical insights on how a number of religious communities
are currently creating successful experiments in recycling within the context of an urban community in Malaysia. The paper
argues that such evidence may demonstrate the ‘potential’ role of religious communities to provide localised resources for
recycling experiments that can be advantageous for the transition towards a more sustainable municipal solid waste management
in Malaysia. The empirical basis of this paper is based on an exploratory multiple case study of successful recycling programmes
conducted by selected religious communities from four key religions in Malaysia—Buddhism, Christianity, Hinduism and Islam.
The theoretical framework for this research is based on the sustainability transitions literature, particularly the ‘transition
experiment’ framework. 相似文献

吐鲁番市历史文化遗址环境生态敏感性综合分析 总被引:1,自引:0,他引:1
针对历史文化资源保护的迫切需求利用高精度的地形数据和生态环境调查资料在GIS技术的支持下进行了历史文化遗址环境生态敏感性评价。以吐鲁番市区的历史文化遗址环境生态敏感性问题为研究对象选取高程等9个敏感性因子,利用层次分析法(AHP)确定敏感性因子权重结合GIS空间分析技术得到吐鲁番市区历史文化遗址环境生态敏感性结果。结果表明:吐鲁番市区历史文化遗址的生态敏感性总体较高,区域差异比较明显。国家级遗址和自治区级遗址都处在高度敏感状态,县市级遗址处在中度敏感状态,急需加强保护。最后提出分类保护措施为今后生态防范措施的针对性提供科学依据。 相似文献

Oasis land-use change and its effects on the eco-environment in Yanqi Basin, Xinjiang, China 总被引:2,自引:0,他引:2

Satellite data and the published coefficients about the world's and China's ecosystem were used to analyze the effects of land-use changes on the ecosystem service in the Yanqi Basin. Both economic developments and arid, fragile ecosystems have strongly affected the land use. A sensitivity analysis determined the effect of manipulating the coefficients on the estimated values. Results indicated that (1) the total value of ecosystem services in the Yanqi Basin were 9,374.66, 10,450.52, 9,964.20, and 9,8707.77 million Yuan in 1990, 2000, 2005, and 2011, respectively. The net increase in ecosystem service values were about 496.11 million Yuan within 1990–2011; (2) The aggregated ecosystem service values of water body, wetlands, grasslands, and croplands were about 99.25 % of the total value; (3) Waste treatment and soil formation were the top two ecological functions with high service values and contributing about 61.70 % of the total service values; and (4) Ecosystem service values estimated in this study were inelastic with respect to the value coefficients; therefore, the estimation was robust in spite of uncertainties on the value coefficients. A reasonable land-use plan should be based on rigorous environmental impact analyses for maintaining stability and sustainable development of the Yanqi Basin. 相似文献

地下水经常不断地参与自然界的水循环,通过从外界获得水量而得到补给,特别是对我们南疆大型灌区而言。地表水是地下水主要补给来源,径流过程中,地表水由补给处输送到排泄处,在水量交换运移过程中,径流同时伴随着盐分的交换与运移,这就是地表水和地下水的循环过程。地表水的补给,径流与排泄决定着地下水的水量与水质在空间和时间的变化,只有对地下水补给、排泄和径流建立起清晰的概念,才有可能正确地分析与评价地下水资源,采取有效的措施,因此据我们目前的各种资料来分析地表水与地下水对比,很有根据和价值。 相似文献
