Research On The Lake-dominant Scenic Spot Planning Based On The Landscape Sensitivity

"A primitive and natural lake has highly sensitive nature to human's activities.With the first residents' settlement by the lake and entertainment projects started in the lake,which began to develop under the influence of humanity."--Li HongyuanEcosystems of lakes have inherent vulnerabilities,therefore,it would be difficult for lakes to recover once it is destructed.At the same time,major crisis is also facing lakes:area atrophying,pollution,eutrophication and so on.The travel of ecotourism is in the marking once again due to the lake's unique charm of the natural landscape,in which case,a higher demand for the programming and construction of lake-dominant scenic spot is needed. However,the present studies of lake-dominant scenic spot mainly focus on such fields as scenic areas planning and tourism development and protection,little was done about comprehensive landscape programming from the viewpoint of ecosystem and landscape ecology.The purpose of this paper is,through the analysis of the landscape sensitivity of lakedominant scenic spot,carrying out scientific planning to protect the highly sensitive region well and develop rationally the weakly sensitive region.The final object it to achieve win-win goals that is not only meeting people's requirement of lakes landscape but realizing sustainable development of resource and minimizing eco-environmental damage.This paper mainly contains two sections.The first part is basal research that includes reviews of lake-dominant scenic spot,which are brief introduction of lakes,landscape area and planning of landscape and lake-dominant scenic spot.The purpose is to know lake-dominant scenic spot basically through the summery.The foIlowing part is the theoretical dominating section in the paper that is the research on approaches of landscape sensitivity analyzing: individual scholars' researches were put into that of visual sensitivity of landscape on the base of common analyzing.That has a significant practical interest on the empirical study in this paper;in visual sensitivity of landscape,this phase is about the researches in such fields as approaches of classifying,ecological gene choosing and analysis of single-gene eco-sensitivity and comprehensive eco-sensitivity.The second part is an empirical study in which Chagan Lake area was taken as an example.Its landscape sensitivity analysis was carried out on GIS platform,and then the planning protection proposals were offered according to the results.The research results of this study are as follows:After the analysis on visual landscape sensitivity of Chagan Lake area,we had a figure of distribution of effective factors;according to landscape visual sensitivity analysis,the regions were divided into four:visually high-sensitive areas,visually relatively higher-sensitive areas,visually medium-sensitive areas and visually low-sensitive areas;according to practical situation,the single-gene analysis on ecological sensitivity was done and grade distribution map of sensitivity was edited;by using the McHarg's graphic overlays,the comprehensive eco-sensitivity analysis of landscape was applied to the four ecological factors.And the region was divided into four parts:ecologically highly-sensitive areas,ecologically relatively-high-sensitive area,ecologically medium-sensitive areas and ecologically low-sensitive areas;according to the analysis on visual sensitivity of landscape,control grade subarea of the visual landscape was partitioned into three parts:visually strictly-protecting areas of landscape,visually controlling areas of landscape,visually reasonably developing areas of landscape;the region was divided into: land-use sites of ecological protection,ecological restoration land and appropriate land for construction purposes according to the analysis on landscape ecological sensitivity;basing on comprehensive analysis,the region of Chagan Lake will be classified as six areas:①ecological preservation②preservation of natural landscape③preservation of historic sites (cultural)④restoration areas of landscape⑤of the district⑥developing and controlling area.The author hopes that this study can supply the scientific theory for the practices of integrating lake-dominant scenic spot programming with eco-program and show its practical significance in the field of landscape ecological construction of lake.
