| A quantitative study was made for the first time on the landscape structure of Ziquejie Core Scenic Spot in Xinhua County.This study was centralized on the landscape ecological planning of this area and supported by remote sensing and geography information system.Firstly a quantitative study of spacial pattern of Ziquejie Scenic Spot landuse was carried out with the methods of remote sensing photograph judgement and on-the -spot investigation.Then based on the results and using GIS technology,the spacial characteristics of mosaic structure,the spacial pattern,ecological process and landscape ecological suitability of residential landscape,forestry landscape as well as terraced paddyfield wetland in the research area were analyzed.So did the Paddyfield culture and Nuo culture.Some problems emerged in the process of constructing landscape were discussed.This study was aimed at providing some scientific evidence for reasonable development and protection of this area.Major study results were as followings:(1) The landscape types of the study area mainly include resident landscape, forestry landscape,terraced paddyfield landscape,river landscape and so on.Forestry landscape and terraced paddyfield landscape have advantage among them.As far as the area composition of the scenic spot was concerned,the forestry landscape area was 2613.88hm~2,the paddyfield landscape area was 1274.25 hm~2,the residential landscape area was 334.99 hm~2 and the river landscape area was 198.94 hm~2 which covered 54.05%,26.34%,6.93%and 4.11%of the total area respectly.The forestry landscape and terraced paddyfield landscape hold all the trumps.(2) The mean area of residential patches in Ziquejie Scenic Spot was small.The patches mostly concentrated in Xixi River spot and the density of resident in this region was the largest,but the residential patches in other spots were dispersed because Xixi River spot located in river valley zone where the altitude was relatively low and flat and without large area forestry.All of these showed there was regional difference definitely among nature conditions and spacial distribution of settlement and obviously affected by landform and so on.(3) There are 2923 forestry patches whose area covers 54.05%of the total area in Ziquejie core scenic spot.The forestry pattern index showed the distribution of the landscape is uneven,the difference among types is large and diversity is small.The degree of homogeneity was small and Cunninghamia forestry take advantage in forestry landscape.The fragmentation is larger and the unity is average.(4) There are 3146 wetland patches in the research area where the rivers and paddyfields were main wetland landscape whose area covered 30.45%of the total area.The range of wetland patches size varied widely in Ziquejie scenic spot where small and medium size patches took advantage in number and the proportion is high. Large patches took advantage in area although their number is less.(5) Through analyzing the Paddyfield cuture and ancient Meishan culture of Ziquejie scenic spot,the paddyfield culture of Ziquejie were devided into two sections: tangible paddyfield culture and intangible paddyfield culture.Ziquejie paddyfield culture has a characteristic of long history,unique style,returning nature,all things on earth having a soul and attaching importance to the harmony between human and nature.(6) Based on the analysis results of residential landscape,forestry landscape, paddyfield wetland and paddyfield culture,suggestion of landscape ecological planning were put forward respectly in order to make use of these resources. Farthermore the paper accomplished Ziquejie core scenic spot overall planning in order to provide the reference for the exploitation and protection of Ziquejie scenic spot.This is the first time to use GIS technology as an assistant tool in scenic spot systematic planning,particularly used in terrace landscape planning.It was a useful attempt for theoretical innovation of scenic spots planning and the other scenic spots planning can take it as a reference in the future. |
