Forest Landscape Pattern Analysis And Sensitivity Evaluation Of Hongtian Village In Fujian Province

There are many researches related to forest landscape planning in my country,but few researches at the village level to improve forest ecological functions and rural forest landscape management.This article takes Hongtian Village,Yong’an City,Fujian Province as an example,supported by landscape ecology and forest management theory.First,it starts with the basic theory of forest landscape and deeply analyzes the relevant theories and technical systems at home and abroad.Second,it uses qualitative analysis and principal component analysis.Method and analytic hierarchy process and other research methods,with the support of Arc GIS and Patch Analyst software,12 landscape pattern indexes suitable for Hongtian village were selected,and the forest landscape types of Hongtian village were divided;afterwards,the forest landscape pattern and dynamic changes of Hongtian village were carried out Analyze and conduct single-factor sensitivity evaluation from the ecological and distance aspects.Determine the weight of each sensitivity factor with the support of the analytic hierarchy process software yaahp,and obtain the comprehensive score of each sensitivity through the comprehensive factor superposition analysis method.Finally,according to the analysis and The evaluation results provide relevant suggestions for the future forest landscape management plan of Hongtian Village.The main conclusions are as follows:(1)The 12 landscape pattern indexes selected from the three major categories of shape index,edge index and size,and density index by principal component analysis have a factor load value of more than 90% in their category.It is a good description of the distribution characteristics of forest landscape in Hongtian Village,and can be used as an indicator for the analysis of forest landscape pattern in Hongtian Village.(2)The overall forest landscape pattern of Hongtian Village presents a distribution pattern dominated by Chinese fir forest and hard broad landscape;the forest landscape area increased significantly from 2011 to 2016,the forest landscape tree species gradually changed to native tree species,and the proportion of introduced tree species continued to decline;The driving force analysis of forest landscape pattern changes shows that the topographic factors are the main influencing factors in natural driving factors,and logging is the main human driving factor influencing the landscape pattern changes in Hongtian Village.(3)The overall evaluation of the forest landscape sensitivity shows that the forest landscape ecological sensitivity is greater than the distance sensitivity.The ecological sensitivity factors,such as altitude,slope and site quality,have a greater impact on the forest landscape distribution,and the slope direction has a greater impact on the forest landscape spatial distribution.Small;the distance sensitivity factor has a greater impact on the overall forest landscape of Hongtian Village;the degree of influence of different sensitivity evaluation factors on the distribution of the forest landscape of Hongtian Village is as follows: buffer distance>site quality>slope>elevation>slope direction.(4)Consider the forest species,dominant tree species,existing management measures,and sensitivity evaluation results to make recommendations for the future forest landscape management plan of Hongtian Village.The principles of forest landscape management planning are proposed,and under the guidance of this principle,7 forest landscape management areas and 13 forest landscape management types are divided according to the results of landscape sensitivity evaluation;the planning of the logging system and afforestation system considers the future forest management objectives,From the landscape scale,the management and management of the forest landscape of Hongtian Village is proposed,and a reasonable method and operation technology suitable for the configuration of the forest landscape structure in this area are proposed to provide a reference for Hongtian Village’s forest harvesting and reforestation in the next five years.By adjusting the spatial distribution of forest landscape types and tree species allocation in Hongtian Village,the ecological stability of the village landscape is maintained,and the economic benefits of the village are improved at the same time.
