Research On The Spatio-temporal Evolution And Regional Protection Of Officially Protected Sites/Entiyy In Shandong Province

The officially protected entities have a rich cultural background.It is an important cultural historical carrier created by human production and life during the long-term historical development,and can show the historical development and changes.Shandong Province has a long cultural history and the officially protected entities have the rich cultural connotations and cultural tourism value.From the perspective of temporal and spatial evolution,this study uses Arc GIS to quantitatively analyze the spatial distribution characteristics and influencing factors of officially protected entities in Shandong Province in different historical periods and types,and on this basis conducting the ecological sensitivity evaluation and classifying the protected areas with different sensitivity levels in Shandong Province.The following results were obtained:1.The distribution of officially protected entities in Shandong Province is unbalanced in space: three high-density core areas and three sub-density core areas are formed.The distribution of officially protected entities are mainly distributed below 100 m in elevation and within 8km buffer zone of rivers;population,economic development and the number of the distribution of officially protected entities are positively correlated,and the distribution of officially protected entities shows certain natural and social characteristics.2.The distribution of officially protected entities in Shandong Province is uneven in time: among the eight periods,the Paleolithic to the Western Zhou period,the Ming and Qing periods,and the modern period have the largest number.This change is closely consistent with the society and the environment at that time.3.The types of officially protected entities in Shandong Province are unbalanced:The number of ancient sites is the largest,followed by ancient buildings,and the number of important modern historical sites and representative buildings ranks third.4.Select 8 factors of elevation,slope,aspect,vegetation coverage,vegetation coverage type,river density,land use type,and road density for comprehensive evaluation of ecological sensitivity,and obtain the weighted analysis comprehensive evaluation of ecological sensitivity and divide 5 levels of insensitive,mildly sensitive,moderately sensitive,highly sensitive and extremely sensitive.5.The data of officially protected entities points and the comprehensive evaluation results of ecological sensitivity are superimposed and analyzed to obtain the distribution of officially protected entities in different levels of sensitive areas,and the sensitivity of the distribution of officially protected entities in Shandong Province is overall moderately sensitive and it has the great value for development.It is divided into four development protection types: moderate development zone,optimized development zone,restricted development zone and key protection zone,and made protection and development recommendations respectively.
