摘 要：
为了进一步分析景观格局与水土流失之间的关系,通过分析研究区2005~2015年景观格局和水土流失的变化情况,得出不同的景观格局类型具有不同的侵蚀模数,合理的景观格局有利于控制水土流失。结果表明:10年间建设用地斑块面积从7 094.47hm~2增加到16 613.28hm~2;10年间研究区的水土流失率先降低后增加,这与城市扩张具有紧密联系,特别是2010年贵州省贵安新区的建设,改变了花溪河流域的景观格局。园地斑块、森林斑块的生态功能、蓄水保土功能强,旱地易产生水土流失。

摘 要：
In order to further analyze the relationship between landscape pattern and soil erosion,it was analyzed the landscape pattern and soil erosion in the study area from 2005 to 2015. The results show that different landscape pattern types have different erosion modulus and reasonable landscape pattern is conducive to the control of soil erosion.The results indicated that the patch area of construction land increased from 7 094. 47 hm~2 to 16 613. 28 hm~2 in 10 years. During the past 10 years,the soil and water loss in the study area has been reduced and then increased,which was closely related to the urban expansion. In particular,the construction of Guian New District in Guizhou Province in2010 has changed the landscape pattern of Huaxi River Basin. The ecological function and water & soil conservation capacity is strong in the garden plaque and forest patches,while the dry land is prone to the soil erosion.
