简介:当为林地生产提起机械化层次时,林地机械的合适的匹配是重要的。在匹配的过程,林地机械不必仅仅为解决问题的专家知识,而且改进方法。我由在一个分析、层次的过程计算各种各样的林地机器的量的参数的类似建议基于盒子的推理的联合(CBR)(RBR)并且基于规则的推理。我计算了在森林工业过去常启用更好的选择的机械的类似并且设备匹配。我建议基于单个参数重量在申请的进程在被修改的偏差的广场的和调整方法的重量值。在系统设计的过程期间,我提出了一个设计方法知识库并且产生了推理的一张动态网集成森林工业的过程的框架机械选择和重量值调整。这启用推理效率的完全的系统和改进的范围的扩大。我用一个实际例子表明这个方法的有效性和有实行可能。
简介:福建省地处我国东南沿海,素有“八山一水一分田”,既是我国森林资源大省,也是我旧南方重点集体林区之一。林业是镉建省的一大优势、一大潜力、一大保障。根据最新全周森林资源清查结果,福建省森林覆盖率已达65.95%,连续36年居全国首位,活立木总蓄积量66674.62万札方米,森林蓄积量60796.15万立方米,商品材产量、林业产业总产值多年来居全国前列。2003年,福建在全国率先进行集体林权制度改革,是全国示范省;2013年全省23个城市空气达标1人数的比率为99.5%,在环境质谴评比中领跑全国。2013年全省林业产业总产值超过3500亿元,年增16%。
