摘要

The western Heilongjiang Province is one of the most important land saline-alkalization region in China. Taking the vector data of land saline-alkalization in 1976 and 2001 as the information source, the paper evaluated the degree of land salinealkalization in the west of Heilongjiang Province, and analyzed spatial-temporal variation characteristics of land salinealkalization by raster technology and ordinary kriging fitting method in Geostatistics. The results showed that the degree of land saline-alkalization was lower than 0.4 except Daqing urban areas in 1976. Furthermore, it took three points as land salinealkalization center, and the field was reduced nearly concentric ring outwards, and degree of land saline-alkalization was generally lower; the land saline-alkalization degree of Lindian county proved to have the largest increase in 2001, the second were Daqing urban areas, Zhaoyuan county and Dumeng county. The land saline-alkalization degree took only one point as center, and the field was reduced nearly coaxial strip of width outwards,, which is generally higher than that of 1976.
