摘要:
冰-草生态交错带是陆地生态交错带的重要组成部分,在全球气候变暖背景下,研究其环境特征对于保护该带脆弱的生态环境具有重要意义。以提孜那甫河流域山区特有的冰-草生态交错带为研究对象,利用MODIS产品,基于遥感技术对其环境特征进行定性、定量分析。结果表明:交错带常年低温,年平均温度为-4.79℃,5—9月气温＞0℃,是主要的融雪期,融雪水量为5.4×108m~3,占提孜那甫河总径流量的70.03%,是叶尔羌绿洲重要的水源补给来源,当年9月到次年5月气温均在0℃以下为主要的积雪期;处在发育初级阶段的寒冻土和寒漠土广泛分布于交错带内,冻融荒漠化普遍且严重,植被分布极为稀疏;交错带主要包含高山流石坡、高山倒石堆、高山稀疏垫状植被等三种极干旱的内陆高原荒漠景观类型。
Abstract:
The Ice-grass ecotone is an important part of Ecotone. Analyzing the environmental features of the Ice-grass ecotone has great significance for protecting the fragile ecological environment under the background of global warming.Take the Tizinafu River Basin mountainous unique Ice-grass ecotone as the research subject, based on MODIS products, using remote sensing techniques for qualitative and quantitative analysis of its environmental characteristics. The results showed that: In the Ice-grass Ecotone year-round low temperature, the annual average temperature was-4.79℃,from May to September temperatures above 0℃, which was the main snowmelt period, the total amount of snowmelt was 5.4 × 108 m3, which accounted for 70.03% of Tizinafu River water runoff. The water is an important water supply of Yerqiang Oasis, in September of that year to the following May with temperatures below 0℃, this period was mainly of snow; In the development of the primary stage of cold-frozen soil and cold-desert soil is widely distributed within the Ice-grass ecotone, freeze-thaw desertification widespread and serious, vegetation is extremely sparse; The Ice-grass Ecotone included stream rock slope, pour rubble, sparsely-vegetated of the high mountain, three extremely arid landlocked plateau desert landscape types.
