Forest and Grassland Landscape Pattern in Xiangyun County
This article employs landscape pattern analysis methods,selects eight landscape indices,and focuses on the characteristics of landscape patches,heterogeneity,and diversity.With the aid of Fragstats 4.2 software and ArcGIS 10.8 software,the forest and grassland landscape pattern in Xiangyun County is analyzed.The results indicate that the forest and grassland landscape type occupies the largest area in Xiangyun County,with a proportion close to 70%,but the total patch number(PN)is less than that of non-forest land;the non-forest land landscape has the largest patch number(PN)(106 605 patches),a relatively large landscape percentage(PLAND)(30.0%),and a small average patch size(MPS)(0.69 hm2/patch).Among the forest and grassland landscape types,the Yunnan pine forest landscape has the largest area(82 877.29 hm2),the highest patch number(PN)(25 626 patches),and the lowest fragmentation index(F)(0.477).Based on these findings,recommendations for the rational allocation of resource elements,strengthening of forest and grassland protection and restoration,and scientific implementation of national greening are proposed,aiming to provide a reference for the scientific management and planning of landscape resources in the region.
