中文摘要：

通过对2002年TM遥感影像（4、3、2波段）的解译并结合土地利用现状图,首先在区域尺度上将研究区（咸宁市）划分出六类农业景观生态功能区,据此又将农业景观类型在不同尺度上划分为广域型景观和镶嵌型景观,其中广域型景观19个,镶嵌型景观（单元）类型36个。在GIS的支持下实现了景观类型图的编绘和空间格局分析,结果显示：（1）中山地天然林区多样性指数最低,为0.111,破碎度指数也最低,为0.016,反映该区景观类型单一,山地林地景观面积和规模较大;而山间盆地农林牧区最高,为0.932,反映该区景观类型多,人类土地利用受地形影响较大;（2）平原高产农业区均匀度指数最高为0.755,反映该区土地利用方式主要受人类控制而有规律分布;（3）低山地用材林区优势度指数最高为0.990,反映该区既受自然条件控制又受人类活动影响,但自然条件占主导;（4）岗台地农林渔区和平原高产农业区破碎度指数较高分别为0.028、0.029,反映该区每类景观面积规模不大,但呈有规律相间分布的特点。在此基础上,根据研究区景观空间格局与自然环境特征,结合生态过程和社会经济需求,提出了该地区农业景观设计的目标和不同类型农业景观的生态设计模式。

英文摘要：

The study area,Xianning city,located in the southern of Hubei Province,China,6 landscape ecological function districts can be derived from composite Landsat 5 TM（Thematic Mapper）images of bands 4,3 and 2 taken in 2002 by interpretation with the map of Land Use.After that,Agricultural ecological landscape type may be classified two types in different scale,namely widespread landscape and inlaid landscape.There are 19 widespread landscape and 36 inlaid landscape in this area.By GIS,obtain the graphic and the analysis of landscape spatial pattern.Studies on landscape diversity indices[Shannon＇s Diversity Index（SHDI）,Shannon＇s Evenness Index（SHEI）,Dominance Index] and landscape spatial configuration indices（Fragmentation and Separation Index）.The results show that：（1）the SHDI and Fragmentation Index of middle mountain district is the lowest,reflecting there are less landscape types but larger area and scale of forest landscape;On the other hand,the SHDI of the basin is the highest,reflecting more landscape types and slightly impacted by human beings;（2）Dominance Index of hills district is the highest,reflecting this area landscape pattern mainly controlled by nature;（3）Fragmentation Index of mound land and plain the higher（0.028,0.029）,reflecting each kind of landscape have a small area,but distributed in rule.According to the study on landscape spatial pattern and the character of natural environment,this paper offers some targets and mode of design for Agricultural landscape in the study area.
