宁夏能源结构低碳优化研究

宁夏的经济结构具有显著的高碳特征,煤炭与电力行业占全区工业产值的近一半比重,工业产值又占据宁夏GDP的半壁江山。低碳时代的到来不可逆转,减碳是对宁夏经济的重大考验与挑战。文章采用灰色关联分析法对宁夏各行业与碳排放的关联度进行了分析,并结合各相关产业区域专业化系数分析,提出了宁夏产业结构升级和能源结构优化的建议。

基于Windows NT服务器的前兆数据共享及其实现

简要介绍了地震前兆数据的现状及其实现数据共享的必要性；分析了常用的二种通用Web数据库的体系结构及应用技术，它们是基于通用网关接口CGI的体系结构和基于服务器扩展API的体系结构。考虑到前兆台网中心硬件设备的条件、所运行的数据库平台和地震前兆数据的复杂性和多样性特点，前兆数据在Internet上的共享服务采用基于通用网关接口CGI的体系结构编写应用程序来实现。以WWW服务器为平台，通过Web服务器方式在浏览器上实现共享，可检索任意台站、任意观测方法、任意地点、任意时段的前兆数据，实现地震前兆数据信息网络服务功能。     

铀在砂岩中的分布

本文指出了外生鈾矿床中金属含量的增高不仅与有机物质粘土颗粒有关,而且与不同的陆源砂粒(噴出岩,长石)的大小有关。确定了组成砂岩的噴出岩和长石顆粒中鈾的含量很高。     

中国及其邻区地震深度的特征

系统地研究了中国及其邻区地震深度的一些时空变化特征后发现：５１％的地震发生在０－１９ｋｍ间，１０、１５、２０ｋｍ为几个地震多发层位；大陆地震的深度小于周邻地区地震的深度；大陆西部地震的深度大于东部地震的深度，这与大陆地壳西厚东薄的结果相吻合；中俄朝交界区及日本海、兴都库什－帕米尔、琉球群岛、缅印交界区和台湾地区地震的深度大，这与有关板块间的相互碰撞、挤压或俯冲等运动有关；兴都库什－帕米尔地区的地震     

川东北石笋120~103 ka BP稳定碳同位素记录与控制机制

利用川东北梭子洞石笋SZ2的稳定碳同位素组成(δ~(13)C)高分辨率重建了120~103ka时段的石笋碳同位素序列。SZ2的δ~(13)C变化与该石笋稳定氧同位素组成(δ~(18)O)的长期变化趋势明显不同。在整体变化趋势上δ~(13)C变化与生长速率相似,反映石笋表面滴水时间间隔影响的CO_2脱气作用和CaCO_3沉积可能是影响SZ2的δ~(13)C长时间尺度上变化的主要因素。但在较短时间尺度上,SZ2的δ~(13)C与δ~(18)O变化基本趋势一致,反映了地表植被类型(如C3/C4植被比例)、植被密度、土壤微生物活动以及洞穴通风效应的变化可能是引起SZ2的δ~(13)C短时间尺度上变化的主要因素。     

区域生态服务价值约束的可持续经济规模量化方法构建

The article conducts a research through theoretical carding, framework construction, and calculation path selection, and concludes that the contribution of ecosystems to human activities mainly comes from the ecological service function. Therefore, based on the relationship between the natural capital stock and flow, ecological services value (ESV for short) or eco-exergy services value (EEV) reflects the output capacity of ecological services. Regional ecological services value is connected to GDP through property ownership and main pressure sources. GDP or the ecological services value reflects the pressure of man-made capital on natural capital. The article attempts to use the ecological services value, eco-exergy services value, and GDP to construct the ecological service output capacity index (R) and pressure index (U), and by introducing the decoupling theory, it proposes a method to “return” the re-coupling GDP to a decoupling state and calculate the sustainable economic scale. It takes Ningdong Energy-Chemical Industry Base in Ningxia as the subject, and has three findings. Firstly, from 2007 to 2017, the economic development and ecological services were in a re-coupling state and the sustainable economic scale was 2.33×10⁹ to 64.3×10⁹ yuan, which was significantly lower than the total industrial output value in the corresponding year. Although the base deploys protection during construction, the R index began to decline after 2015, and there exists a risk of degradation. Secondly, the method uses the “declining turning point” of the R index to mark the bottom line, and attempts to put forward a quantitative method of regional sustainable economic scale from the perspective of the internal generation principle of the ecological contribution of capital value, which is helpful to the analysis method of reasonable population size, green GDP and ecological compensation. Thirdly, combined with the decoupling theory, the method can analyze the boundary of economic scale under regional ecological constraints, which has certain application value to enrich evaluations methods on sustainability.
