Frozen soil is a widespread kind of soil at high altitudes and high latitudes. It is divided into two parts, permafrost and seasonally frozen soil. It accounts for about 79% of northern hemisphere. As the largest country in the world, the area of Russia frozen soil occupies a large proportion. The use of satellite remote sensing technology has promoted the rapid development of permafrost research since 1970s. In this paper, NOAA remote sensing data preprocessing in Asian part of Russia was done. According to the band characteristics of AVHRR data, split window algorithm was used to calculate surface temperature. Thus, interpreted permafrost and seasonally frozen ground were interpreted, and added up the change of frozen soil area. The conclusion of this research is that permafrost is being degraded to seasonally frozen ground every year. In the end of this paper, the reasons and the hazards were analyzed.

几何矩是用于推导平移、伸缩和旋转不变量的常用技术。用直接方法计算矩涉及大量的加法和乘法,因而有必要研究几何矩的快速算法。该文首先综述现有的对几何矩进行快速计算的顺序算法,然后用数字实验比较Delta方法、多线段积分方法、以及Li和Shen的格林定理法的性能。多线段积分方法和Delta方法在计算Hu矩不变量方面性能是相同的,但Delta方法仅适于处理二值水平连续图像,而多线段积分方法可以处理任意二值图像。与Li和Shen的格林定理法相比,多线段积分方法在计算精度上性能很完美。

景电灌区次生盐渍化土壤冻融特征

土壤学报 2002年第4期39卷 512-516页

通过对景电灌区一个冻融周期的现场观测,发现盐渍化土壤冻结期缩短,冻结深度减小,冻结起始位置不是地表,而是位于地表以下某个深度,这导致在冻结发展期间有两个冻结锋面出现,使水热盐动态更为复杂。

1997年我国实施了西部大开发战略,西部地区的生态环境问题再次引起多方面的关注。“西部金睛行动计划”的实施旨在通过具有代表意义的7个典型区同步监测西部10年(1990～2000年)来的生态环境变化情况,为国家西部大开发战略提供科学的决策支持。项目采用遥感与地理信息系统技术相结合的方法,按照8个统一的原则,制订了生态环境遥感监测技术指南,对这些地区在1990年和2000年的生态环境变化进行了动态监测。监测结果表明,这10年来,由于人类活动加强,农业用地、城市用地大量增加,挤占了自然/半自然植被区,草场过牧引起草场退化,致使典型区生态环境仍处于逐渐恶化的状态。
