Riassunto

本书源于森林测高器研究之博士论文，其内容针对目前生产中现有工具不适于密林测高的实际情况，通过对三角原理测高方法的归纳、分析和拓展性思维，创新性设计出了四种新型测高工具：它们是任意点测高器、准连续可变距式测高器、旋轮式测高器和改进式克里斯屯测高器。对于每种设计来说，作者都从设计背景、初步构思、方案筛选和制作方法方面进行了详细的论述，这为读者学习、理解和利用本书提供了方便。本书的理论基础是三角原理，应用对象是森林调查，中心问题是森林测高，研究重点是工具的易用性和可靠性。书中内容不仅为林业调查提供了新的实用性装备技术，对提高森林野外调查水平、保障外业数据的可靠性和准确性有益，而且，设计和研制中采用的“连续”和“准连续”的设计思想、能够有效增加读数盘设计面积的旋轮结构、以及首次提出的基部被挡时一次性测定树高的理论，对于三角原理类测高器的改进设计具有重要意义。在读者方面，本书不仅适合于林业调查技术人员阅读使用，同时也可作为环保、建筑、采矿、仪器设计等相关行业中具有三角测量工作背景的学者和工程技术人员参考使用。另外，由于书中对三角原理测高的理论和历史进行了系统的归纳整理，对世界上不同历史时期的森林测高器资料进行了分类和收集引用，所以，本书亦可为从事几何学和三角学研究的学者提供相对丰富的应用案例。
