Based on the studies on the siltation and lake shrinking,changes of water environment and habitats of Grus nigricollis, utilizations of wetland resources, relations between ecological environment changes and current functional zone dividing model are discussed. The protection management of ecological environment under current functional zone dividing model is not effective in solving the conflicts between resources utilization and protection of the wetland. It is necessary to study ecologic structure and function of Caohai plateau wetland.

通过对草海国家级自然保护区水土流失、湖盆淤积，水环境、黑颈鹤栖息生境等生态环境特征变化以及当地社区湿地资源利用状况的分析，探讨了湿地生态环境变化与现行保护区功能分区的关系，说明三级模式下的湿地生态环境管理激化了湿地资源利用与保护的矛盾，必须加强草海湿地生态结构和功能特征的研究，制定合理的保护区功能分区，切实有效地保护湿地生态环境。

In modern researches on the grain-size characteristics of lake sediments, the methods of incertical dividing sediments grain-size have no rigorous mathematical theory to support. To resolve this omission, the case of pollen zonation was taken for reference. 338 samples measured by Mastersizer 2000 from DG02 core of Gahai lake in Qaidam Basin were studied. Considering the clustering results of sequential clusters did not change the sequence of samples, tilia software package was used to divide the dividing sediments grain-size.

针对现阶段湖泊沉积物粒度特征研究中垂直剖面分层方法所存在的数学方法的不足，借鉴孢粉分带比较成熟的案例，应用有序聚类法中次序不变的特点，以柴达木盆地尕海湖DG02钻孔338个经激光粒度仪测试的样品为研究对象，在有序聚类的数学理论基础上，借助Tilia软件将湖泊沉积物垂直剖面进行分层。

Thirdly, in order to manage these data better, the paper advances the organization methods of data of commixed Database of Geo-spatial Framework model by integrating some advanced database technologies such as RDBMS and the Spatial Database Engine, namely on the basis of database and the data of Geo-spatial Framework divided in a preceding part of this paper, it describes layer-delaminating, block-dividing, slice-connecting, map-dividing and BLOB etc. to organize spatial data, including DLG, DOM, DEM, and thematic data, taking example for the data of urban planning. At the same time it also realizes integrated management of these data.

然后，本文以管理这些地理空间框架数据为主要目标，集成关系数据库管理系统以及空间数据引擎等相关技术，提出了地理空间框架混合数据库数据组织方法，即以地理空间框架数据库为基础，以分类后的地理空间框架数据为对象，通过采用分层、分块、连片、分幅以及大二进制对象等方法对基础空间数据(包括数字线划数据、数字正射影像数据、数字高程模型数据)和专题数据进行统一组织，并实现了这些数据的关联一体化管理。
