Evaluation Of Human Activity Intensity In Danxiashan Scenic Area In Guangdong Province Based On Human Influence Index(HII) Model

The quantitative evaluation of the human activities intensity is the basis for analyzing the influence of human activities on the environment of scenic spots.The Danxiashan Scenic Area is a key scenic spot in China and a world natural heritage resource.The scenic area is rich in geological and forest resources,long-term cultural and historical resources,consequently there are huge development potential.At the same time,the balance of the protection and development of the scenic area is particularly important.In the development and construction of the scenic area,there are human activities of different degrees and scopes,which cause potential disturbances and threats to the ecological environment of the scenic area.At present,there are relatively few studies on the spatial-temporal distribution and change trend of human activity intensity in the scenic spot of Danxiashan.The qualitative and quantitative evaluation of the human activities in the scenic area is of great significance to the sustainable development of the ecological environment.In order to evaluate the human activities intensity in the scenic area,this article is based on the Human Influence Index model and combines the characteristics of Danxiashan Scenic Area in Guangdong Province to build an appropriate human activity intensity evaluation system.This article uses related planning,statistical and public data to convert them into spatial data in Arc GIS software.Then,we obtain the human influence index and human influence map of 2009,2018 and 2025 at the scale of 30 m × 30 m.This paper uses the above calculation results to compare and analyze the distribution and changes of human activity intensity in the scenic area from the three dimensions of scale,time,and weight.And then this paper puts forward corresponding protection and utilization recommendations based on the analysis results.Finally,the following conclusions were obtained.1)In the scale comparison study,it is verified that the evaluation results using 30 m × 30 m scale data can guide the management and optimization of scenic spots in space.For the Danxiashan Scenic Area,at the scale of 1km×1km,the average human impact index is large,the area of the affected area in the scenic area is large,the impact of the affected area is high,and the "naturalness" in the scenic area is low.On the contrary,the 30 m × 30 m scale study provides more accurate calculation results and richer spatial information,which can assist the optimization of scenic spots.2)In the time-space comparison study,the average HII from 2009 to 2025 ranged from 3 to 9,and the human activity intensity as a whole was at a "low" level.However,with the continuous development and utilization of scenic spots,the average value of the HII has continued to increase,from 3.12 in 2009 to 8.53 in 2025.The growth rate is slow first and then fast.The area not affected by human activities decreases year by year,and the rate of decrease is slower and faster.In addition,the average HII during the study period of each scenic spot: Danxiashan Scenic Area> Jinjiang Scenic Belt> zhenjiang Scenic Belt> Bazhai Scenic Spot> Feihuashui Scenic Spot> Xianrenji Scenic Spot> Shaoshishan Scenic Spot.The longer the development time,the higher HII.3)In the weight comparison study,according to the characteristics of Danxiashan scenic spots,this article uses the expert scoring method to determine the weight of 10 evaluation indicators to obtain a localized evaluation system.There is a significant difference in the HII before and after the use of weights.And after using the weight,the average value of human impact index increases.In general,the focus of this article is to use the human influence index model,combined with the characteristics of Danxiashan scenic spots,to build a human activity intensity evaluation system of Danxiashan scenic spots.The characteristic is to use social media materials as supplements to realize the quantitative assessment of the impact of tourists.Therefore,the evaluation system for the intensity of human activities at the scenic area scale was improved.Quantifying the influence degree and influence range of human activity intensity through space provides a new idea for the planning and management of scenic spots.
