项目摘要

Experimental plots were established in a secondary forest dominated by mizunara oak (Quercus crispula). DBH and height of all trees on the plots were measured and sample oak trees were felled just outside the plots. The biomass of each tree organ was measured and other root variables such as root length, area and volume were also measured. First, equations to estimate the root variables from other tree variables were created. Missing root parts were estimated from the diameter of broken root ends with regression equations created between the four root variables and root diameter. Allometric regressions between root variables and other tree variables were analyzed both by root diameter classes and for the total root system. DBH proved to be a good predictor of root variables for different root classes and for the total root system. Second, the growth process of stand volume and tree volume for an old closed hardwood secondary forest was modeled. A growth equation for predicting volume g … More rowth from stem volume was derived under biological assumptions on respiration and photosynthesis. Parameters of the equation were estimated from the stem volume at the time of measurement and their latest growth of the stem-analysis trees.Species composition in secondary hardwood forests was estimated using measurements on plots and GIS. The study area was forest around Takigashira Bog and in Akashibayama national forest, in Niigata Prefecture. The subject species were Siebold's beech (Fagus crenata), konara oak (Quercus serrata) and mizunara oak, which were dominated in this area. Species composition was investigated in sample plots, and DEM was created from digitized contour lines. The relationship between relative basal area and topographical and environmental factors calculated from the DEM was examined using multiple regression analysis and regression equations were derived. Applying the equations on GIS, the relative basal area of main species was estimated and mapped.The leaf area index (LAI) in natural deciduous hardwood forests dominated by Siebold's beech, konara oak and mizunara oak was estimated based on topographical features, using a GIS. Twenty-two plots were selected in the area, and four litter traps were set in each plot. The dry weight of leaves collected in the litter traps was measured, and LAI was estimated for each plot. The relationship between LAI and topographical factors was analyzed, based on type I quantification theory, and an equation to predict LAI from elevation and slope was derived. The LAI in deciduous broad-leaved forests was estimated and mapped for the area using the derived equation. Less

试验地建立在以水杉为主的次生林中。对样地上所有树木的胸径和高度进行了测量，并在样地外砍伐了橡树样本。测定了各器官的生物量，并测定了根长、根面积、根体积等根系变量。首先，建立了从其他树变量中估计根变量的方程。通过建立四个根变量与根直径之间的回归方程，根据断根末端的直径估计缺失的根部分。分析了根系变量与其他树木变量之间的异速生长回归，包括根径等级和整个根系。对于不同的根级和整个根系，胸径被证明是一个很好的根变量预测因子。其次，模拟了老封育阔叶林林分蓄积和林木蓄积的生长过程。预测g…材积的生长方程根据呼吸作用和光合作用的生物学假设，从茎体积得出更多的生长量。方程的参数是根据测量时的树干蓄积量和树干分析树的最新生长量来估计的。次生阔叶林的物种组成通过样地测量和地理信息系统来估计。研究区域是新泻县高桥村沼泽周围的森林和赤桥山国家森林。研究对象为西伯德山毛榉(Fagus Crenata)、柯纳拉栎属(Quercus Serrata)和米祖纳拉栎属(Mizunara Oak)，它们是该地区的优势种。在样地中调查物种组成，并根据数字化等高线创建DEM。利用多元回归分析方法研究了相对断面积与地形环境因子之间的关系，并建立了回归方程。在地理信息系统上应用这些方程，估算并绘制了主要树种的相对断面积，利用地理信息系统根据地形特征估算了以山毛榉、柯纳拉栎林和水曲柳栎林为主的天然落叶阔叶林的叶面积指数(LAI)。在该地区选择了22个地块，每个地块设置了4个凋落物陷阱。测定了在凋落物陷阱中收集的树叶的干重，并估算了每一样地的叶面积指数。基于第I类量化理论，分析了叶面积指数与地形因子的关系，推导了由高程和坡度预测叶面积指数的公式。利用导出的方程对该地区落叶阔叶林的叶面积指数进行了估算和绘制。较少
