Abstract：网络舆情一定程度上是现实社会矛盾在网络空间的投射和延伸，是社会的晴雨表。新媒体时代，人人都有“麦克风”成为现实，多元主体参与社会治理的意识愈发强烈，促使网络舆情汹涌澎湃，呈现出突发性、复杂性、群体极化性、传播速度快、潜在危害大、易反转等特征。网络舆情风险无处不在，无时不有，种种原因的叠加促使网络舆情态势复杂严峻。网络舆情已对国家安全、人民认知、社会稳定、政府公信力构成极大影响，网络舆情治理已然成为国家治理和社会治理的重要组成部分。本文从网络舆情柔性治理、多元治理、法制治理、技术治理等层面展开研究思考，试图提升网络舆情防范化解水平，为构建和谐稳定的网络生态和社会环境提供支撑。

Abstract： 由于对陆地生态系统土壤、植被碳蓄积量了解的缺乏，故在预测气候变化中存在较大分歧，因此很有必要对不同生态系统碳分布情况进行研究。本文以干旱盐湖为研究对象，探究盐湖生态系统碳分布特征。结果表明：土壤有机碳密度分布随土层深度的增加而降低，土壤无机碳呈无规律分布；100 cm土层内有机碳密度介于7.55~15.75 kgm-2之间，平均为12.54 kgm-2，占植物群落和土壤总有机碳密度的97.84%。黑果枸杞和铃铛刺为盐生群落的优势种，地上平均生物量为261.38 gm-2，占总生物量的70.49%，草本植物群落平均生物量仅为109.45 gm-2；灌木和草本层地上生物量显著高于凋落物层（84.819.22）gm-2和（79.768.61）gm-2。盐生植物地下生物量随土层的增加而降低，0~100 cm土层总地下生物量为77.74 gm-2。盐生植物总生物量碳密度为276.48 gm-2，其中地上、凋落物和地下生物量分别占62.09%、25.75%和12.16%；地上植被和凋落物碳密度显著高于草本植物，根系生物量碳密度在剖面上分布不均，96.55%集中在0~50 cm土层。盐生植物地上地下以及凋落物平均碳含量43.09%，与经验系数（50%）换算得到碳密度相比实际碳密度高出13.80%，这将对植被碳储量的估算产生较大的偏差。

Abstract： [Purpose/significance] In line with the national intellectual property strategic development, some university libraries have tried to develop intellectual property information services in recent years. Since the intellectual property information service breaks through the original information service, it is urgent to train a batch of librarians with corresponding service capabilities. In addition, as an important source of intellectual property, university library directors, researchers and students' intellectual property information literacy needs to be improved. Therefore, it is necessary to establish a complete and standardized training system for intellectual property information services in universities.[Method/process] This paper used literature research, expert interviews, questionnaires and other methods to conduct extensive research on four groups of universities, and built a multi-agent intellectual property information service training system. The training content has five modules:intellectual property awareness strength, intellectual property basic knowledge, intellectual property information retrieval, intellectual property information analysis and application, as well as intellectual property application process explanation and patent document writing. Among which basic knowledge, information retrieval, information analysis and application were key modules, which were divided into primary, medium and high levels. The modular course can be assembled to implement the training.[Result/conclusion] The training system has the advantages of completeness, operability and adaptability. It can meet the needs of multi-level and diversified intellectual property training in universities. Its effective implementation will improve the intellectual property information service capabilities and intellectual property information literacy.
