摘　　要：利用湖北、湖南、贵州三省第二次土地利用调查数据,从平原区、丘陵区和山地3个研究区中随机各选取50个镇,测算其景观指数和生态服务价值,然后通过逐步回归分析研究二者之间的关系。研究结果表明:1不同生态区的景观格局存在差异,且不同地区不同类型的生态服务价值存在差异,这主要是由各地的地理位置、海拔高度和地形的差异以及人类活动的干扰和需求引起的;2不同生态区景观格局与生态价值的相关程度不同,平原区景观格局与单位面积生态价值的回归,入选变量多,联系更密切,相关程度高;3景观格局的差异在一定程度上影响生态价值,而生态价值间接反映了景观格局的优劣。人类活动剧烈会导致对生态的干扰增强,景观格局的局部集聚与蔓延,使景观脱离自然原生形态,但不一定导致生态服务功能的下降,该扰动也可是正向的。Using the second national land survey's data of Hubei, Hunan and Guizhou, this paper randomly selected 50 towns from the landscape maps of plain region, hilly region and mountain region, and calculated the landscape index and ecological service value. And then, the paper explored the relationship of the landscape index and ecological service value by regression analysis. The results show that 1 landscape pattern in different ecological zones is not same, what's more, the diversity of ecosystem services exits in different zones. This is mainly caused by geographical differences, elevation and topography and disturbance of human activities. 2The degree of correlation of landscape pattern and ecosystem services value are different in different areas. 3The difference of landscape pattern can affect the ecological service value in a certain extent, and ecosystem services value indirectly reflects the layout of the landscape pattern. The intense human activities can lead to increasing interference to ecology, local agglomeration and spreading of landscape pattern. The result is landscape will be in isolation from the original morphology of nature, and the destabilization maybe is positive so that the decline of ecosystem services does not always occur.
