耕地与基本农田保护态势与对策

, 2004
全国土地利用变更调查结果显示,1996～2003年全国净减耕地数量为6704万hm2,年均净减少9577万hm2。为此,应探讨耕地保护的调控模式和机制,确定耕地数量保护和耕地质量改善目标以及耕地生态建设目标;并对不同时期的目标进行分解,使其成为各地方、各层次主体的实际行动目标。通过重建耕地价格机制,建立行之有效的耕地保护机制。基本农田作为耕地的精华,是耕地保护的主要内容和手段。为此,要特殊保护一级基本农田,要改进基本农田损失补偿制度,加强基本农田保护区信息系统建设 ...

基于红外相机技术的野生环颈雉行为谱及PAE编码系统

野生动物学报
动物行为谱和PAE（posture-act-environment）编码系统的建立有助于行为学数据的科学量化和深度分析。以广布种为研究对象开展此类研究，能为揭示物种行为多样性特点及其生存适应机制奠定重要基础。为科学量化野生环颈雉（Phasianus colchicus）的行为数据，2019年7月—2021年4月，以天津盘山风景名胜区野生环颈雉为研究对象，基于红外相机技术首次建立了该物种野生种群的行为谱及PAE编码系统，并与其圈养种群行为多样性进行比较讨论。共获得野生环颈雉有效照片1 207张 ...

计及雷击浪涌传输效应的输电线路避雷器优化配置方法

Dianci bileiqi
安装输电线路避雷器(Transmission Line Surge Arresters, TLSA)是改善架空输电线路(Over Head Transmission Lines, OHTL)防雷性能的解决方案之一。基于此，提出了一种基于多目标优化算法和ATP(Alternative Transient Program)软件的OHTL避雷器新型优化配置方法。该方法通过考虑避雷器运行引起的雷击浪涌的传输效应，进行雷击闪络率计算，而已有文献中很少提及这种可导致相邻架空铁塔的转移机制。最后，在某实际230 ...
