【摘要】 基于2006年和2016年丘北普者黑省级自然保护区的森林资源二类调查数据,综合运用数理统计和景观生态学理论和方法,对普者黑自然保护区2006-2016年土地利用和景观格局变化进行研究。结果表明,自然保护区各地类在10年间均向其他用地类型进行相互转化,按各地类变化面积排序为:农用地>有林地>灌木林地>水域>未成林地>宜林地>未利用地>建设用地>非林地>苗圃地>疏林地;按各地类面积增加排序为:有林地>灌木林地>建设用地>疏林地>无立木林地>非林地>水域>未利用地>未成林地>宜林地>农用地。研究区主要以农用地、有林地、灌木林地、水域和建设用地为优势景观;这几类景观斑块分布相对分散,切割程度和破碎化程度增加。在景观尺度方面,景观斑块总体呈现出多样化、破碎度、形态复杂化;不同类型景观的团聚程度、延展性和连通性减弱,分布离散性增强,呈现出非均衡性、异质性趋势变化的景观格局。更多还原

【Abstract】 Based on the forest resources survey of Puzhehei Provincial Nature Reserve in Qiubei in 2006 and 2016,the land use and landscape pattern changes of this reserve in these two were studied using the methods of mathematical statistics and theories of landscape ecology.The results showed that all types of land use in nature reserve were transformed to other types of land in 10 years,and the ranking in term of changing area was:agricultural land>woodland>shrub land>water area>unmatured forest land>suitable forest land>unused land>land for construction>non-woodland>nursery land;and the ranking in term of increasing areas was:forested land>shrub land>land for construction>open forest land>forest land timber>non-wood land>water area>unused land>unmatured forested land>suitable forest land>agricultural land.The dominant landscapes in the study area were agricultural land,woodland,shrub land,water area and land for construction.These landscape patches were relatively dispersed,and the degree of cutting and fragmentation increased.In terms of landscape scale,landscape patches were generally diversified,fragmented and complex in shape;the degree of agglomeration,extensibility and connectivity of different types of landscape were weakening,and the dispersity of distribution was increasing,and showed a changing landscape tendency of non-equilibrium and heterogeneity.更多还原
