【摘要】 贵州山多平地少,了解万亩大坝的土地利用结构类型及其动态,有助于协调万亩大坝中建设用地扩展和耕地保护的矛盾。本研究以GIS为技术支撑,应用景观生态格局的分析手段进行万亩大坝土地利用构成及其格局差异研究,结果表明:①所研究的39个连片平坝,土地利用结构可分为耕地主导型、建设用地耕地主导型、耕地林地主导型3类,以耕地主导型为主。②耕地主导型坝子耕地斑块的平均面积超过30 hm~2。③以耕地利用为主的坝子景观单一,城镇活动增加,使坝子耕地变破碎,景观多样性增加。更多还原

【Abstract】 As the mountains of Guizhou province are more than flat ground,so,to understand the land use structure types and its dynamic change of Wanmu flatlands is contributing to the coordination of contradiction between the expansion of construction land and cultivated land protection in the Wanmu flatlands.This paper studied the land use constitution and its spatial pattern of the Wanmu flatlands based on the CIS for technical support and landscape ecological pattern analysis method.The results indicate as flows:①the land use structure of the 39 piece continuous flatlands can be divided into 3 types which are dominant by cultivated land,construction land and cultivated land,cultivated land and woodland respectively,but most of these flatlands are the first types,②the average area of cultivated land patches are more than 30 hm~2 in flatlands dominated by cultivated land.③the landscape of flatlands dominated by cultivated land is simple,and the increasing town make cultivated land be in a fragmentation,at the same,the landscape diversities increase.更多还原
