| 摘 要： | 利用河南省土地利用现状数据，对河南省土地利用现状进行分析，并在此基础上运用景观格局指标对研究区域土地利用的空间格局进行定量分析。结果表明：①河南省优势景观类型为耕地，其面积占土地总面积的65%左右，其次为建设用地和林地，其它面积较小的景观类型则呈补丁状散布在各个分区中；②由于自然条件和人类活动干扰的双重作用，造成河南省土地利用景观格局存在明显的空间差异，在地形起伏较大的山地丘陵地区，景观的多样性和均匀度相对较高，景观优势度则相对较低；在人类活动强烈的平原地区，农业景观类型具有明显的主体地位，景观则呈现较低的多样性性和均匀度，而在生态环境相对较为脆弱的山地平原过度地区，加上高强度的人类活动对土地利用的影响，致使这些地区景观破碎化程度较高。

| Abstract: | By employing land-use data in Henan province, this article interpret and draw a remote sensing map of Henan province with the help of GIS and RS techniques. The landscape spatial patterns of land-use in research area were quantitative analyzed by using landscape indices. The results show that the dominant pattern of the landscape in Henan province is farm land; the proportion of its total area accounts for about 65 percent of all sub-areas, being followed by construction land and forest land. Forest land is mainly located in the northern, western, southwestern and southern mountains of Henan province. Urban construction land is inlaid in the whole research area, whose distribution pattern is closely related to cultivated farm land. Other patch types are distributed 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. 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. 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. This is because the effect of human agricultural production activity in the highlands and mountainous areas is minor. In comparison, strong human disturbance and agricultural development reduced landscape diversity in the plain area. 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. Finally, the author suggests that more measures should be taken to improve the ecological environment and promote rational utilization of land resources in Henna province, especially in ecological fragile transitional zone. |
