In this paper, taking Nieruzanghu as an example, it is discussed that how to plan landscapes of small basin in the qinghai-tibet plateau. With analyzed the status and character of landscape structure through the use of landscape diversity indexes and landscape dominant indexes, some major problems in the landscape ecosystem are pointed out. On the basis of regional restrictive principle and compliance principle of resources, environment and economy, Nieruzangbu Basin is divided into three landscape function areas. According to the demands of each function area, landscape structure planning is carried out to improve ecological environment through optimization and adjustment of landscape structure in Nieruzangbu Basin.

Taking Niyang River Basin as an example, applying with the indices of landscape pattern, the indices of ecological risk of ecosystems are calculated in this paper, which takes the value of ecological loss of main ecosystem as the evaluation standard and takes into account the impacts of probability or the velocity of main hazards and event of the ecosystem. And the grades of ecological risk are assessed. According to the results of assessment, the ecological risk grades of the basin are divided into five classes. From the first grade risk to the fifth grade risk, the values of regional risk indices gradually reduce. The first grade risk areas mainly distribute in Niyang river and its branches downstream and the surrounding areas of main towns. And the basin area of non-valley region and the headstream regions of the branches are the fifth grades risk areas. This evaluation results provide the basis to the regional sustainable development.

本文基于对历史图像的微观分析，就中国与世界的关系进行了宏观思考。本文认为，梁启超《新史学》中所谓的“世界之中国”，并非只是最晚进的“近世史”阶段的特征，而是包括“上世史”“中世史”在内的中国整体历史的特征。作为文化和空间双重视域的“中国”，正是在与“世界”不断交接过程中逐渐建构起来的。本文进一步区分了“大中国”和“小中国”的视域，一方面，认为可以通过传统图像关于“昆仑”的艺术想象，学习到具有重大历史潜力的新的空间和地理范式；另一方面，还指出了这一空间和地理范式背后所依据的真实的自然地理格局：是青藏高原的崛起导致印度洋和太平洋上双向循环的季风模式，形成亚、欧、非三大洲，以及地中海、黑海、红海、印度洋与太平洋诸文明之间来来往往、相互交流的自然节律，从而为世界文明相互需要的整体性，以及全球史和跨文化艺术史的研究，提供了自然与地理的基础。
