锦州市土地利用景观格局及其生态环境效益分析

基于2015年的锦州市土地利用图形数据,选用生态意义较明确的景观特征指数,从景观和斑块类型两个尺度水平上定量分析了辽宁锦州市的景观空间格局,并揭示了景观格局对区域生态环境的影响。结果表明:(1)旱地景观是锦州市面积最大、分布最广、连续性最强的基质景观;林地景观面积比例也较大且斑块数最多。(2)位于渤海辽东湾的区域其景观格局基本呈现出旱地、林地景观类型镶嵌分布的特征,近海位置有水田、沼泽等水域景观。(3)人为破坏干扰了其景观空间结构的复杂性,影响自我调节能力,以至于没能发挥出其作为沿海城市靠近水源的区域优势,需要进一步改善环境。

Landscape pattern and ITS Eco-environmental benefit analysis in Jinzhou City

Basing on the sketch date of land use in the year of 2005, using the more explicit landscape metrics wequantify and analyze the landscape spatial pattern in Jinzhou and in term of plate scale and landscape scale to reflect the affect of landscape pattern on regional eco-environmental. The result shows: (1)Dry land landscape is the biggest in area, the most extensive in distribution, and the strongest in consecution substrate landscape in Jinzhou. Wood land landscape is the second biggest in area, which is the biggest. (2)That located in the Bohai sea fishing area, the landscape pattern on the regional reflects the feature of mosaic of substrate landscapes of dry land, woodland landscape type. Offshore position paddy field, swamp and other waters land-scape. (3) The man-made destruction, interfere with the land-scape spatial structure complexity, influence the self-adjustment ability that you can't play it as coastal cities close to the water source conversation area advantage, it is necessary to further improve the environment.
