基于传统土壤图的土壤—环境关系获取及推理制图研究

在数字土壤制图研究中,从历史资料中提取准确的、详细的土壤—环境关系对于土壤图的更新和修正十分重要。从传统土壤图中提取土壤类型并从地形数据中提取环境参数,采用空间数据挖掘方法建立土壤—环境关系,并进行推理制图和精度验证。以湖北省黄冈市红安县华家河镇滠水河流域为例,首先选取成土母质和基于地形数据提取的高程、坡度、坡向等7个环境因子;然后利用频率分布原理得到包含土壤类型与环境因子信息的典型样本数据1 410个;采用See5.0决策树方法进行空间数据挖掘,建立土壤—环境关系;将其导入So LIM中进行推理制图;最后利用270个实地采样点验证所得土壤图的精度。土壤图的精度提高了约11%,证明了本研究方法对土壤类型和空间分布推理的可靠性。     

Stem Diameter Estimation from Aerial Photographs

Remote sensing techniques have proven successful for producing stem maps of forests in leaf-on condition from high-resolution imagery. This paper demonstrates how a mathematical model for the surface of a stem can be used to estimate the breast-height diameter of individual trees from aerial photographs to give information on basal area. The diameters are estimated by likelihood estimation from images of a forest in leaf-off condition where the stems and their shadows are visible. Applied to a homogeneous and monospecific oak ( Quercus robur L.) stand under standard silvicultural treatment in Denmark, the estimation was successful for 56 out of 60 trees. The root mean squared error on the diameter was 4.2 and 3.2 cm using three and five images, respectively. The key conclusion is that it is feasible to infer fairly accurate information about the diameters and three-dimensional positions of stems from aerial photographs.

应用模糊c均值聚类获取土壤制图所需土壤-环境关系知识的方法研究

在没有土壤普查专家及土壤图的地区,获取土壤环境间关系的知识是基于知识进行预测性土壤制图中的关键问题。本文建立了一套应用模糊c均值聚类(Fuzzyc-means,FCM)获取土壤环境间关系知识的方法:得到对土壤形成发展具有重要作用的环境因子,建立环境因子数据库;对环境因子进行模糊聚类,得到环境因子组合隶属度分布图;根据隶属度值确定野外采样点;将环境因子组合与土壤类型对应,进而提取土壤-环境关系知识。为检验该方法的有效性,应用所得知识进行土壤制图,通过独立采样点对土壤图进行精度评价。本文在黑龙江鹤山农场一个研究区的应用结果表明,该方法仅需要少量的野外采样即可获得有效的土壤-环境关系知识,为预测性土壤制图提供必需的依据,同时也显著提高了野外采样的效率。

Virtual plant based on fuzzy neuron Inference of physiology process

A fuzzy neuron inference of physiological process (FNI-PP) based virtual plant growth model is proposed. Using machine learning theory, the model can automatically learn and fit the plant growth function according to measured data and extract the plant growth rules. During plant growth, the source and sink organs respond the surrounding virtual environment according to its inbuilt growth function, and produce, allocate and consume assimilates as well as update the L-grammar representing the plant structure. The model can automatically adjust parameters of the growth function and the L-grammar to respond the environmental heterogeneity. Cayenne-based simulations show that the model can accurately extract the growth function and the structural pattern of the plant, and vividly demonstrate the response to environment.
