川西高原马尔康旅游气候舒适度分析与评价

为了更好地发展旅游事业,在对马尔康旅游资源做出具体规划的同时,对当地的气候资源特征进行分析与评价。利用马尔康县气象站1966~2005年逐日气温、相对湿度、风速、降水量等观测资料,计算当地温湿指数、风寒指数、着衣指数、综合舒适指数等,进而对旅游气候舒适度进行定量分析与评价。研究结果表明:(1)马尔康地区温湿指数和风寒指数分别在7、8月份达最大值,着衣指数在7月份达最小值,人体在7月份感觉最舒适;(2)40a间,马尔康地区温湿指数,风寒指数和着衣指数总体变化较稳定,个别年份波动较大;(3)1966~1990年,舒适天数基本在125d左右波动;受全球变暖影响,1990~2005年马尔康舒适天数呈明显波动上升趋势。这说明马尔康夏季为最适宜旅游季节,全年大概有120d非常适宜旅游,旅游资源丰富,且气候变化对当地旅游资源开发有明显促进作用。

ENVIRONMENTAL CHANGE AND ITS IMPACTS ON HUMAN SETTLF, MENT IN THE CHANGJIANG RIVER DELTA IN NEOLITHIC AGE

Dating data, altitude of Neolithic sites, climatic changes from sedimentary records and previous research results were collected and analyzed to detect possible connections between climatic changes and human activities in the Changjiang River Delta in the Neolithic Age. The results indicated that hydrological changes greatly impacted the human activities in the study region. Low-lying geomorphology made the floods and sea level changes become the important factors affecting human activities, especially the altitude change of human settlements. People usually moved to higher places during the periods characterized by high sea level and frequent floods to escape the negative influences from water body expansion, which resulted in cultural hiatus in certain profiles. However, some higher-altitude settlements were not the results of climatic changes but the results of social factors, such as religious ceremony and social status. Therefore, further research will be necessary for the degree and types of impacts of climatic changes on human activities in the study area at that time.     

Water Requirements and Irrigation Scheduling of Spring Maize Using GIS and CropWat Model in Beijing-Tianjin-Hebei Region

Due to the over use of available water resources, it has become very important to define appropriate strategies for planning and management of irrigated farmland. In this paper, Beijing-Tianjin-Hebei (Jing-Jin-Ji) region was chosen as the case study area for its special political and economic status and its severe water problem. To achieve effective planning, the information about crop water requirements, irrigation withdrawals, soil types and climatic conditions were obtained in the study area. In the meantime, a GIS method was adopted, which extends the capabilities of the crop models to a regional level. The main objectives of the study are: 1) to estimate the spatial distribution of the evapotranspiration of spring maize; 2) to estimate climatic water deficit; 3) to estimate the yield reduction of spring maize under different rainfed and irrigated conditions. Based on the water deficit analysis, recommended supplemental irrigation schedule was developed using CropWat model. Compared to the rainfed control, the two or three times of supplemental water irrigated to spring maize at the right time reduced the loss of yield, under different scenarios.

射洪县近30年区域气候特征分析

利用射洪县近30年来的气温、降水、相对湿度、云量、日照时数等气象要素资料,应用多种统计方法分析了近30年来射洪县的区域气候特征.结果表明,射洪年平均温度在1986年左右发生转折性变化,气温明显变暖.而年降水量总体上以波动变化为主,在20世纪80年代中后期有较为明显的减少.降水量与年平均温度的突变年代类似,但变化趋势正好相反,说明90年代以后射洪的气候向暖干型转变.各气象要素的综合分析表明,随着全球气候变暖,射洪区域气候变化趋势不容乐观:相对湿度的减少导致降水减少,而温度则在进一步上升,低云量的增加和日照时数的减少,使得阴天寡照加剧.射洪区域气候变化与当地诸如人口增长,城市扩大等人类活动,以及农业生态之间均存在密切联系.     

Isotopic and chemical analyses of a temperate firn core from a Chinese alpine glacier and its regional climatic significance

Mt. Yulong is the southernmost currently glacier-covered area in Eurasia, including China. There are 19 sub-tropical temperate glaciers on the mountain, controlled by the south-western monsoon climate. In the summer of 1999, a firn core, 10. 10 m long, extending down to glacier ice, was recovered in the accumulation area of the largest glacier, Baishui No. 1. Periodic variations of climatic signals above 7. 8 m depth were apparent, and net accumulation of four years was identified by the annual oscillations of isotopic and ionic composition. The boundaries of annual accumulation were confirmed by higher values of electrical conductivity and pH, and by dirty refreezing ice layers at the levels of summer surfaces. Calculated mean annual net accumulation from 1994/1995 to 1997/1998 was about 900 mm water equivalent. The amplitude of isotopic variations in the profile decreased with increasing depth, and isotopic homogenization occurred below 7. 8 m as a result of meltwater percolation. Variations of δ18O above 7. 8 m showed an approximate correlation with the winter climatic trend at Li Jiang Station, 25 km away. Concentrations of Ca2+ and Mg2+ were much higher than those of Na+ and K+ , indicating that the air masses for precipitation were mainly from a continental source, and that the core material accumulated during the winter period. The close correspondence of C1- and Na+ indicated their common origin. Very low concentrations of SO2-4 and NO3- suggest that pollution caused by human activities is quite low in the area. The mean annual net accumulation in the core and the estimated ablation indicate that the average annual precipitation above the glacier's equilibrium line is 2400 - 3150 mm, but this needs to be confirmed by long term observation of mass balance.
