辽宁省辽河流域景观格局变化研究

利用遥感和GIS技术，分析了2000-2010年间辽宁省辽河流域景观格局的特征与变化。结果表明，随着经济的发展、城镇化水平的提高，土地利用变化使得辽河流域景观格局特征向着破碎化的方向发展，流域各景观类型的分布趋向均匀化。辽河流域各类生态系统主要向城镇转变，其中农田向城镇转出面积最大，主要分布在沈阳北部、东部、铁岭南部和盘锦市部分地区；流域农田景观向湿地类型的转移，主要分布在辽河干流及流域北部康平境内的卧龙湖西南部分地区。为了保证辽河流域景观格局合理性，保护流域生态系统功能，建议开展生态规划，控制城镇类型景观的无序扩张，划定生态保护红线并实行严格的管理制度。

Researches on the Changes of Landscape Pattern in Liao River Basin

In order to understand the characteristics and changes in landscape pattern during 2000-2010,remote sensing and GIS technology were chosen to study Liao River Basin in Liaoning Province.The results showed that with the development of economy and the promoting of the urbanization level,the landscape pattern of these areas was more fragmented and the type diversity increased.In Liao River Basin,the landscapes mainly converted into the urban landscapes during 2000 to 2010.The area converted from farmland to urban landscape was the most,which mainly distributed in the north and east of Shenyang,the south of Tieling and the part of Panjin city.The district converted from farmland to wetland landscape was mainly distributed in the Liao River main stream and the part of southwest of Wolong lake in Kangping in the north of the basin.Ecological planning,ecological protection red line and the strict management system were suggested to prevent urban sprawl,protect ecosystem function and ensure the suitable landscape pattern in Liao River Basin.
