Paper Abstract

The conjugated evolvement between land use/cover change (LUCC) and landscape pattern are appeared as their relevancies in space-time scale. In this paper, the data resources are combined the conventional maps and statistics with two temporal TM images in the middle and lower reaches of the Hanjing Basin in 1995 and 2000, and the system analysis are made to the coefficient of land use intensity (the COLUI), composite index of landscape pattern (the CILP), and their changes. The platform of spatial data processing is software ERDAS and ARC/INFO, and the attribute data are calculated with software ACCESS, EXCEL and SPSS. The results of statistical and correlation analysis show the rules of conjugated evolvement between LUCC and landscape pattern, that is, there is a remarkable negative correlation between the COLUI and the CILP in this region. In 1995, the correlation coefficient between the COLUI and the CILP is -0.572 with the confidence level 0.01, it means that the probability of negative correlation is 99%. In 2000, this correlativity is increased, the correlation coefficient is -0.683 with the confidence level 0.001, meaning that the probability of negative correlation between the COLUI and the CILP is 99.9%. The spatial analysis shows that the correlativity is associated markedly with relief types in spatial distribution in the study region. The correlativity between the indexes in the plain and mountainous regions is higher than in the hilly county, meaning that the land use structure and landscape pattern are illogicality. In the hilly county, the COLUI and the CILP are high, but the correlation is illegibility, meaning that the land use structure and landscape pattern are in reason. The temporal analysis shows that the degree of correlation is trended to increase with time.
