摘要

The landscape spatial pattems of land-use in Henan province were quantitative analyzed by using landscape indices in the article. Four landscape ecological indices, such as landscape diversity index, landscape dominance index, landscape fragmentation index and landscape evenness index were chosen to analyses the landscape spatial patterns of land use in research area. There was an obvious spatial difference in landscape spatial patterns of land-use in Henan province, because of the double effects of natural conditions and human activities. The results show that similar change trends were observed in all sub-areas in landscape diversity and evenness indices, but the change of landscape dominance index was reverse to landscape diversity and evenness indices. The landscape diversity and evenness indices in highlands and mountainous areas are higher than that in other sub-areas; however landscape dominance index is higher in plain areas than in highlands and mountainous areas. On the other hand, landscape fragmentation index of the transitional zones between mountainous region and plain is higher than that of others because of the influences of stronger human disturbance and weak ecological environment in those regions. The double effects of natural conditions and human activities have intensified landscape fragmentation process.
