| 摘 要： | 将景观生态学的理论与兰州南北两山环境绿化工程的实际相结合，运用景观格局分析方法、GIS（ARC/INFO）和数理统计等多种方法，在绿化工程景观评价指标研究的基础上，研究了兰州南北两山环境绿化工程区域按坡度分布的景观格局特征。结果表明：兰州市南北两山各个分级坡度上景观多样性均不高，除0°~9°上的大于1外，其余的均小于1。各个分级坡度上景观格局指数、各指标的组合状况值、景观格局综合指标值总体上符合随坡度增加而减小的趋势。但40°~49°的景观格局指数、各指标的组合状况值、景观格局综合指标值比30°~39°的景观格局指数、各指标的组合状况值、景观格局综合指标值稍大，这是因为40°~49°上的林地和农地的斑块数较30°~39°的多，且占本坡度所有土地面积的比例也大于30°~39°的。兰州市南北两山各个分级坡度上景观格局指数、各指标的组合状况值、景观格局综合指标值在0°~9°上均明显高于其他坡度地区的。 |

| Abstract: | By methods of landscape pattern analysis, GIS(ARC/INFO), and mathematical statistics, we studied the characteristics of spatial landscape pattern according to slope of afforestation in southern and northern mountains of Lanzhou city, based on study on the quantitative evaluation indexes of afforestation pattern. The results show that: the landscape diversity in each slope level is low, and all are less than 1 except for the 0°~9° slope region; in each slope level, the landscape pattern indexes and their assembled status level as well as the synthesized level of the quantitative evaluation indexes are all generally decreased along with the increase of slope. But there is an exception, those of 40°~49° slope region are all slightly larger than those of 30°~39° slope region due to more figure spots of forest and farmland and also their area ratio in the 40°~49° slope region. Among all the slope levels, those indexes in the 0°~9° slope region are obviously the highest. |
