为完成泸西县白水烤烟“十二五”8 200.00 hm^2基本烟田规划与景观格局趋势分析,利用Patch Analyst4.0软件测定拼块数量(Num P)、香农多样性指数(SDI)、香农均匀度指数(SEI)、平均形状指数(MSI)、平均拼块分维度(MPFD)、拼块面积方差(PSSD)、核心拼块面积(CA)等10项参数,进行遥感影像群判读技术与景观格局分析。结果表明:(1)香农多样性指数SDI值“十一五”规划4.625较“十二五”规划SDI值大0.008,而新规划MPFD值1.359较原规划值增加0.04,体现出原规划景观类型较多、新规划景观格局分离度则显著加深等规划特点;(2)“十二五”核心拼块面积规划值CA较“十一五”大4 331.345,反映出新规划按照规模化、集约化原则,体现出布局合理、重点突出等规划特点。
In order to accomplish the " Twelfth Five-Year" 8 200. 00 hm2 basic tobacco field planning on Baishui of Luxi County, Yunnan Province and its landscape pattern analysis, a group-based image interpretation theory and Patch Analyst 4. 0 landscape pattern analysis method for determining NumP, SDI, SEI, MSI, MPFD, PSSD, CA was introduced. The results showed that : ( 1 ) The SDI value decreased from 4. 625 to 4. 617 and the MPFD value increased from 1. 319 to 1. 359, indicated less land- scape type and deeper separating degree Evolutionary trend; (2) The CA value increased from 3 868. 686 to 8 200. 031, reflected the planning fitting large scale and intensive principle, with a reasonable layout and focused planning characters.
