First of all, retreat of glaciers and shrink of perennial snowbank induced by climate warming provide parent materials and spatial room for soil formation and development in the maritime Antarctica. Meanwhile, melt water originating from glaciers and snow-ice covers enhances temporal and spatial availability of free water, which plays all-important roles both in periglacial processes and the processes within soil profiles, thus influencing soil genesis and evolution to a great degree.

This project was conducted starting with the three interrelated subjects the structural characteristics of desertification landscapes in different bioclimatic zones, desertification driving factors and their function mechanism, and the dynamic model of landscape space for the occurrence and development of desertification in representative desertification regions and on the basis of in-depth studies of the relations between landscape structural characteristics and processes of desertification and their stability; the driving force of different time-space scales of desertification and their proportion, manifestation form, and action mechanism in the desertification processes; and the establishment of threshold conditions for the surface wind erosion and has achieved important progress in the definition of desertification conception

本课题从三个相互联系的专题（即不同生物气候区荒漠化景观的结构特征、荒漠化驱动因素及其作用机理、典型荒漠化地区荒漠化发生与发展的景观空间动力学模型）入手，在深入研究荒漠化景观结构特征与过程的关系及其稳定性，不同时空尺度的荒漠化过程驱动力及其在荒漠化过程中所占比重、表现形式及作用机制，地表风蚀临界条件的确定等内容的基础上，虽未建立荒漠化景观空间动力学模型，但在沙漠化概念，末次间冰期以来沙漠化过程时间序列和特征冷暖时期沙漠、沙地空间分布格局，现代沙漠化过程中自然因素和人文因素的作用、贡献率、沙漠化土地对气候的反馈作用以及风蚀临界值，沙粒跃移轨迹参数和能量分布，我国沙漠化防治思路和对策，沙尘暴区划和沙尘暴指数等方面取得了重要进展。

This paper focus on the 3 LiaoYuan Regionalization ——mild-wettish zone in the northwest part, warm-cool half wettish zone in south central part and cold-cool half wettish zone in east part, according to agriculture natural climatic resources in LiaoYuan, and refer to the local unique physiognomy and topography , apply the heat and moisture factor target-oriented, relying on Precipitation in growth period of April-September as the Auxiliary index of General Ways invagination.

本文根据辽源地区的农业自然气候资源，参照本地独特的地势地貌，采用以热量和水分因子为主导指标，以4-9月生长期降水量为辅助指标的综合套叠方法，将辽源地区划分为西北部温暖湿润区、中南部温凉半湿润区、东部冷凉半湿润区三个农业生态气候区，旨在为当地党政机关合理开发利用气候资源，科学调整农业结构和布局，减轻和避免气候灾害，提供科学依据和参考。

Reference crop evapotranspiration (ET0) and new wetness index were both calculated and analyzed according to Penman-Monteith scheme recommended by FAO with routine meteorological data from 616 weather stations in China from 1975 to 2004. In terms of grades of wetness index from Chinese Climate Classification Criterion, China is classified into severe arid, arid, semi-arid, semi-humid and humid zones, respectively, which are compared with the demarcations from rainfall-based indices in order to reveal the similarity and difference in association with the two schemes under current global climate warming. Besides, the spatio-temporal analysis of climate wetness over the country in the past thirty years was performed.
