基于Landsat 8遥感数据的天津市地表温度反演

以Landsat 8遥感数据为数据源,进行天津市地表温度反演研究。首先采用单通道算法反演地表温度,并利用均值标准差法进行温度分级。然后建立不同温度等级面积比例的估算模型。再通过随机样点,从不同温度等级和土地覆盖类型2个角度,分别建立并比较不同类样点的地表温度与各指数的拟合模型。结果表明:次高温区域面积比例与人口密度、人均GDP都具有较高的决定系数;地表温度与NDVI、BAEM的二元线性回归决定系数高于地表温度与单一指数的决定系数;将样点分类后,低温点与MNDBI的决定系数高于其他温度等级样点,水域和植被样点与各种指数的决定系数高于其他地物类型样点。     

“三权分置”下农地细碎化治理的社会路径及其效果、效益分析——基于“沙洋模式”的考察

基于湖北省沙洋县农地细碎化治理经验，分析了在“三权分置”改革背景下，开展农地细碎化治理的社会路径及其效果、效益。研究结果显示：（1）农民对农地细碎化治理的需求较强，“三权分置”改革可以增强农民的土地获得感和土地调整能力，使他们既作为农地细碎化治理结果的“受益者”，又作为农地细碎化治理过程的“主导者”；（2）借助“承包权”和“经营权”的分离，稳定农户的“承包权”，调整细碎耕地的“经营权”，使“承包者”与“经营者”都可以获取合理的产权预期；（3）地方政府和村集体在土地调整过程中发挥着协调与整合的重要作用，它们通过如理性计算与长远规划等具有地方特色的策略，能够有效提高农地细碎化治理的执行效率。研究发现：农地细碎化治理的社会路径可以实现较好的治理效果，并具有显著的经济效益和社会效益，有助于维护农村的社会稳定与可持续发展。研究建议：伴随农地确权工作进程，当前是实现农地细碎化治理的较好契机。全国其它地区可以结合村庄实际、地方资源与农民需求，选择诸如“经营权”流转、互换等多种适宜的土地调整形式，有效破解农地细碎化困境，进一步提高我国农地资源配置效率。     

大肠杆菌吸附-化学还原法用废含金催化剂制备金纳米线

采用大肠杆菌吸附-化学还原法,以大肠杆菌(ECCs)为模板、十六烷基三甲基溴化铵为保护剂、抗坏血酸为还原剂,由废含金催化剂制备金纳米线(AuNWs)。采用XRD,SEM,TEM等技术对AuNWs进行表征。研究了AuNWs对罗丹明6G(R6G)和4-巯基苯甲酸(4-MBA)的拉曼散射信号的增强效果。实验结果表明:在制备过程中加入微生物ECCs,可使金回收率提高约20百分点;当溶液pH小于4时,反应2 h后,有大量呈线状的AuNWs聚集沉降,金回收率可达99%1以上。表征结果显示,AuNWs呈多晶结构,晶格间距为0.23 nm。表面增强拉曼散射分析表明,AuNWs对R6G和4-MBA具有良好的拉曼光谱增强性能。
