| 摘 要： | 利用遥感技术和地理信息系统等技术手段,基于MODIS数据对我国2005年的草原植被长势进行监测。结果表明:2005年全国草原植被长势总体上比2004年略差,并呈现“前期较好、后期较差”的时间演变特征;长势好的区域主要分布在内蒙古东北部、青藏高原东部青海与四川交界区域、新疆天山北部等区域,总体长势差的区域则分布在内蒙古中部、西南地区,以及西藏西南高山草原等地区;重点省区草原长势变化各异,例如内蒙古总体长势与2004年接近,但时空分布不平衡,而西藏前期长势好于2004年同期,后期则差于2004年同期。

| Abstract: | The grassland vegetation growth relates to the overall growth state of the area.The integration of 3S(RS,GIS,GPS) with MODIS data was used to monitor the grassland growth of 2005.Some conclusions are drawn as follows:(1) Grassland vegetation growth throughout the country was slightly worse than that of 2004.(2)The grassland vegetation was featured as "growing better in the early but worse in the late period of the year".(3)The 2005 better-growth area included the grassland of northeastern Inner Mongolia,that of the border area between Qinghai and Sichuan provinces,east of the Qinghai-Tibet Plateau,and grassland of the northern Tianshan Mountains of Xinjiang Ughur Autonomous Region.The poorly growing area consisted of grassland in the central and the southwestern Inner Mongolia Autonomous Region,and the southwestern alpine grassland of Tibet Autonomous Region.(4)The vegetation growth of the various important provinces and regions with vast grasslands differentiated one from the other.For instance,the overall growth of the Inner Mongolia grassland in 2005 was basically the same as that in 2004,though the area and the time length of the healthy and scanty growth were different.In Tibet,the vegetation growth in the early period of 2005 was better than that in the same period of 2004;but worse in the late period of the year than that of the previous year. |
