摘要:
 以海口市为研究样区,基于RS和GIS技术,采用景观格局和缓冲区梯度带分析相结合的方法,研究海口市景观格局空间分布和梯度变化特征。结果表明,全市以乔木林和农地景观为主,从主城区向外,沿着缓冲区梯度带,其景观面积比例和边缘密度均呈现出下降的趋势,而不透水表面和草地景观格局则表现出相反的状态,且都在第3区以后趋于稳定。在城市外缘5~15 km的城乡融合区域是城市地表覆被变化最为激烈的地带,呈现斑块形状多样、复杂、破碎的分布格局,景观多样性很高。研究认为,城市化和人为干扰是影响景观格局空间梯度分布差异的重要因素。
Abstract:
 Based on the RS and GIS techniques,the spatial distribution and gradient characteristics of landscape pattern in Haikou were studied by using the combination of landscape pattern and buffer gradient zone analysis.The results showed that the whole city mainly consisted of the arbors and farmland landscape.Landscape area ratio and edge density showed a downward trend from the main urban area to the outside along the buffer gradient zone.However,impervious surface and grassland landscape pattern showed a contrary tendency,and both of them later stabilized in the third district.In desakota region (5-15 km from the city),the land cover changed most significantly,showing diverse,complex and broken patch distribution pattern with high landscape diversity.Urbanization and human disturbance were considered important factors influencing the spatial gradient distribution of landscape pattern in Haikou.
