Remote sensing is used to d et ect forested area and identify forest characteristics such as tree height, bio- mass and density.
为了利用微波遥感数据对森林植被地区进行分类检测,寻找一种新的敏感于树木高度、种群数量和植被疏密程度等森林特征的遥感参量,该文利用中国天山地区SIR-C/X-SARL波段全极化干涉数据,对极化散射矩阵总功率、极化熵、相似性参数和极化干涉最优相关系数等极化和干涉合成孔径雷达(SAR)遥感参数进行了分析,并将这些参数进行加权组合,利用特征值分析方法求取最优加权系数,从而提出两种对森林特征敏感的参数组合表达式。
Based on the game theory and its methods,this paper analyzes the decision-making when it comes to the concession term in urban water supply BOT projects,establishes a dynamic game model of complete information between the investor and the government,and finds the optimal decision-making model by deduction,thus providing a systematic method for determining the concession term.
利用博弈论的理论和方法,研究了城市供水BOT项目特许权期的决策问题。
This paper sets up a model in which the project company decides its investment scale and the government decides the concession term under the condition that demand increases constantly with time.
在需求随时间不断增长情况下,建立了BOT项目公司进行投资规模决策和政府进行特许权期决策的模型,求得了项目公司的最优投资规模决策和政府的最优特许权期决策,并对影响双方决策的变量进行了讨论,结果表明项目公司的最优投资规模不是特许权内完全满足市场需求的最大规模,且其投资规模应随特许权期的延长、项目设计寿命的增加和产品价格的上升而扩大。
