Abstract: As the most basic production unit, eco\|economy systems of farming and grazing households are of significance to the implementation and outcome of national policies. In this paper, eco\|economy systems of farming and grazing households, in Mu Us sandland acrossing Inner Mongolia Autonomous Region and Shaanxi Province,were studied by emergy theory and emergy analysis methods. The emergy input and output structure of different industrial models in Wushen banner, where grazing is dominant, and Yuyang district, where farming is the case, have been compared and analyzed. The total characteristics of pattern and development of typical eco\|economy systems of farming and grazing households are described and compared quantitatively by net emergy output ratio, emergy investment ratio, environmental loading ability, emergy power density, productivity of unit acreage, emergy cost per capita, emergy possession per capita, system production priority, system stability index and sustainability index. We hope our study could help to provide strategies for development and optimization of farming and grazing household industrial models in farming\|dominant zones and grazing\|dominant zones of Mu Us sandland.

Abstract: Aiming at real productivity of frail farming and grazing ecosystems in Mu Us sandland, basing on coupling theory of complex ecosystem, Uxin banner where grazing is dominant and Yuyang district where farming is the main character were selected as research object by means of using emergy theory and analytic methods, it analyses the primary productivity, secondary productivity and the coupling status of the farming and grazing system in those two areas for 27 years. And it comes up with a possible evolvement regulation of the extent of agro-ecosystem coupling. The results show that the industrial development model of Yuyang distric is farming-dominant, but Uxin banner is the grazing-dominant; Yuyang district has the tendency of pig, poultry production, but Uxin banner has the tendency of herbivorous animal production; the primary productivity, secondary productivity, A, B and SCD in those two areas are all increasing, and the SCD has the increase in the shape of "three-stage" in 27 years. In conclusion, this paper brings forward the developmental methods of farming and grazing ecosystems coupling in Mu Us sandland, it is expected to provide credible theory supports and direction to healthy development of the farming and grazing ecosystems.

Abstract: 农、牧户单元生态经济系统作为最基层的生产单位,关系着国家大政方针政策的落实和实施。运用能值理论及其分析方法,选择毛乌素沙地偏牧区的内蒙古自治区乌审旗苏力德苏木典型牧户生态经济系统和偏农区的陕西省榆阳区牛家梁镇典型农户生态经济系统作为研究对象,对两种不同产业偏重区产业模式的能值投入、产出结构状况进行对比分析,结合净能值产出率、能值投资率、环境负荷力、能值功率密度、单位面积生产力、人均能值用量、人均能值占有量、系统生产优势度、系统稳定性指数和系统可持续性指数共10项能值分析综合指标体系,全面系统地对农、牧户单元生态经济系统进行比较研究,定量描述典型农、牧户单元生态经济系统格局及其发展的总体特征。旨在为毛乌素沙地偏牧区和偏农区农、牧户经营层面的产业模式优化及发展提供策略选择。
毛乌素沙地农牧生态系统能值分析与耦合关系

Abstract: 针对毛乌素沙地脆弱农业生态系统生产力实际,根据复合生态系统耦合理论,借助能值理论及分析方法,选择毛乌素沙地偏农区的榆阳区和偏牧区的乌审旗为比较研究对象,对两地近27a的农牧耦合系统初级生产力、次级生产力及系统耦合状况进行了对比分析,探讨性提出了区域农牧系统耦合程度的演变规律。结果表明,榆阳区是偏农型的农牧耦合产业发展模式,乌审旗是偏牧型的牧农耦合产业发展模式;榆阳区有以耗粮型生猪、禽类生产为主的势头,乌审旗有以节粮型草食动物生产为主的势头;榆阳区和乌审旗的初级生产力、次级生产力及a(有效能值利用率)、b(单位低质能产品转化成高质能产品率)、scd(系统耦合度)值均沿时间序列增大,且scd值有呈三阶段型增长的规律性。依据研究结果,最后提出了毛乌素沙地农牧生态系统耦合发展的途径,以期能为沙地农牧生态系统稳健发展提供可靠的理论支撑与政策导向。

Abstract: ?采用双子季铵盐对蒙脱土进行有机化处理,再与环氧树脂进行插层复合制备了环氧树脂/蒙脱土复合材料。借助xrd和ftir等手段对改性蒙脱土进行了表征,对复合材料的力学性能进行测试。结果表明,改性使蒙脱土层间距增大,有机蒙脱土的加入改善了环氧树脂基体的力学性能,当有机蒙脱土质量含量为1%时,其弯曲强度、冲击强度等力学性能得到了最大的提高。
和谐话语与抗争文化:当前农村社会治理的新机制
harmonious discourse and protest culture: the current rural social governance mechanisms

Abstract: 本文主张通过政治话语“和谐”来导引抗争文化,寻找当前农村社会治理的新机制。农村社会的抗争文化与抗争事件密切相关,往往经过长时间的沉淀比较稳定。近年来,随着形势的发展变化,集体公共文化不断弱化,抗争事件中政治因素趋向增强,使得抗争文化转向“激烈”。通过引导地域文化、关注抗争过程、尊重司法结果,化解抗争政治,使得基层治理更加有序。通过重建公共领域文化、引导外来多元文化及去除抗争性的文化,使其转向“温和”,从而达到治理的目标,形成和谐有序的社会秩序。
This article argues to find the current rural social governance mechanisms by guiding contention culture by political discourse "harmony", contention culture of rural social is closely related to incidents, and is often stable after a long time of precipitation. In recent years, with the development of the situation changes, weakening the collective public culture, politics tends to increase in the event, the contending culture becomes "intense". Through the guide the local culture, respect the process and justice as a result, dissolve the struggle and political, the grassroots governance more orderly. By rebuilding public domain culture, guiding foreign cultural diversity and removing the contend culture, make its turn to "moderate", thus achieve the purpose of the governance, forming a harmonious and orderly social order.
