该方法主要是充分利用二元光学法和液晶空间光调制的各自优点，并按照设计系统的要求，最大程度避免二元光学法使用不灵活而液晶空间光调制激光能量利用率不高的缺点，实现温度分布均匀化系统优化。

A framework is proposed for modeling spatial distribution of population density. The study region is divided into fine grids. Kernel estimation is used to break down count data published for one fixed set of irregular areal units to the grids where the population is uniformly distributed. The spatial continuous surface which reflects a truer p...

将研究区域划分为一定分辨率的格网，用核心估计方法将人口密度估计值分配到每个格网上，每个格网上的人口是均匀分布的，随着格网分辨率的提高，就可以模拟出符合人口详细分布的人口密度空间连续分布模型，并通过实验说明该方法是可行的。

Moreover, we discuss the geo spatial information value-added services network, which will be formed on the internet in the future, and the development and prospects of GIServices. The development mechanism of geo spatial information service model is summarized.

分析了每种模式的空间信息流模型与增值过程，并讨论了适合的空间信息服务应用，以及在Internet上未来会形成的空间信息增值服务网络，展望了空间信息服务的大众化发展方向。

The research is about the reuse of urban sewage for virescence irrigation, and the influence of sewage irrigation on eco-environment such as soil, plant, etc. is studied. Under the condition of field sewage irrigation, the transport and transformation and accumulation mechanism of heavy metals, nutrients and organic pollutants as vaporizable hydroxybenzene etc. in the soil-plant system are analyzed. The heavy metal pollution is evaluated by the comprehensive pollution index. The spatial variability of heavy metals in sewage irrigation area is further understood. The spatial variability of heavy metals and physical and chemical properties of soil are reflected in a more straight way by the theory model of variance function curve based on the geographical information system.

在城市污水回用于绿化灌溉对土壤、植物等生态环境的影响研究中分析了大田条件下污灌对土壤-植物体系中重金属、养分及挥发酚等有机污染物迁移转化及富集机理，对重金属污染进行了综合污染指数评价，进一步了解了污灌区重金属分布的空间异质性，基于地理信息系统提出了变异函数曲线的理论模型，更直观地反映出了重金属元素与土壤理化参数的空间变异特征。
