摘要:
研究区域不同梯度带土地利用景观变化特征，可为维持区域生态功能、改善区域生态环境质量提供科学依据。以松嫩高平原典型地域巴彦县为研究区，利用ArcGIS手段，以地形因子（高程、坡度）作为研究区梯度分级基础，考虑地貌类型和行政区划划分梯度带，应用梯度分析和景观格局分析相结合的方法，从景观水平和景观类型水平两方面，分析研究区13 a来不同梯度带土地利用景观变化特征。结果表明：（1）1996—2009年间，梯度带Ⅲ土地利用景观破碎化程度最大，受人类活动的影响最严重；梯度带Ⅱ优势景观比较明显，土地利用景观结构稳定性最差。（2）1996—2009年，各梯度带土地利用景观基质均为旱地，水田景观所占比例均有所上升，且各梯度带林地景观所占比例差别一直较大，建设用地景观增长水平基本一致。
Abstract:
Study on the variation characteristics of regional different gradient zones of land-use landscape aimed at providing a scientific basis for the maintenance of regional ecological function and the improvement of regional ecological environment quality. The typical area of Songnen High Plain—Bayan County was selected as the study area，by means of ArcGIS, using the topography (elevation, slope) as the study area gradient classification standard at the same time considering geomorphic types and administrative division of the gradient zones, and by gradient analysis and landscape pattern analysis methods, from two respects of landscape level and landscape type level the land-use landscape characteristics of different gradient zones during 13 years were studied. The results showed that: (1) from 1996 to 2009, land-use landscape fragmentation of gradient zone Ⅲ had maximum strength, so human activities had the biggest influence on it, dominant landscape of gradient zoneⅡwas quite obvious, so the structure stability of land-use landscape was the worst; (2) 1996—2009 land-use landscape matrix of every gradient was dry land, the proportion of paddy field increased, the proportion of woodland landscape of various gradient zones was significantly different, and the growth of construction landscape of every gradient was at the same level.
