景观格局分析法与土地利用转换矩阵在土地利用特征研究中的应用

研究目的:以黄河三角洲为例,研究景观格局分析方法与土地利用转换矩阵在土地利用特征研究中的应用。研究方法:景观格局分析和土地利用转换矩阵。研究结果:近20年山东省来东营市的土地利用主导变化过程是耕地、城镇建设用地、农村居民点用地增加,天然草地大量减少,土地利用类型有向单一化发展的趋势。这种土地利用模式对黄河三角洲地区发展、湿地保护是不利的,应该引起足够的重视。研究结论:将景观格局分析法和土地利用转换矩阵结合,可以快速的对一个地区的土地利用特征进行定性理解和定量分析,为政府管理部门提供数据支持和决策依据。

Application of Approach of Landscape Pattern Analysis and Land Use Conversion Matrix in Research of Land Use Characteristics

The purpose of the study is to apply the approach of landscape pattern analysis and land use conversion matrix in research of land use characteristics,taking Yellow River Delta as a case.Methods of landscape pattern analysis and land use conversion matrix were employed.The results show the arable land,urban land,rural residential land have increased and natural grassland decreased in large amount in recent 20 years.The pattern of land use type trends to be less diversified,which is unfavorable to the development of Yellow River Delta and the protection of wetlands.The combination of landscape pattern analysis with land use conversion matrix approach can be contributive to qualitative and quantitative analysis to land use characteristics in an area quickly,also to the decision making of administrative departments of the government.
