The 21st century,with the green life,eco-tourism has become a hot,people are starting to recognize that the natural landscape value with local characteristics and personality.As an important part of a natural landscape,landscape ecology of the forest not only plays a significant role in the improvement and restore the natural ecological environment,but also has higher aesthetic value of the humanities.How to create a scenic forest ecological research scholar at home and abroad scientificly and rationally has become an important issue.In this paper,ecological landscape forests aesthetics,theoretical foundation,and ecological landscape forests judge on the basis of ecological forest landscape quality evaluation and transformation.The main findings summarized as:(1)Ecological landscape forest is an important natural landscape and the main material foundation of ecological tourism construction.It is also an important research object of landscape ecology.Now how to construct ecological landscape forest has been concerned by designers.In order to make sure the reliability of the model,we use evaluation method of scenic beauty and analysize the results of the same landscape that made by different major population in different judgement ways.The results show that there is no obvious difference in evaluation results,so the evaluation datas have high reliability.(2)To evaluate the quality of ecological scenery forest landscape,psychophysics was selected.And its advantage was that,first,landscape value was evaluated on the basis of public assessment,which could effectively reduce the effect of expert judgment and subjective supposition;second,physical characteristics of forest landscape could be measured objectively or more objectively,which could avoid the inconveniences caused by many applications of principles beauty of format as diversity and the peculiar,as well as the application of some other ecological principles.(3)The acquisition of ecological scenery forest evaluation picture should try to avoid external factors such as visibility,light intensity ect.which could impact on the aesthetic value.And the shooting time should mainly be the choice of flowering period,leaf changing period,fruit maturation period,ect.The shooting was mainly head up.For a more rational and scientific evaluation of the landscape,the same brand,the same type of camera should be adopted.Because of the limitations of the ability to identify the impact of this evaluation,one landscape was represented by one photo.(4)Evaluation of the value of beauty was treated with standardization as dependent variable of model building;and the value of landscape elements(including qualitative and quantitative)as the independent variables.Then different types of landscape assessment model was built by the selection of number of multi-model.Also,spring view(types of view and non-flower pattern), summer view,autumn view and interior forest landscapes was established.Finally,the establishment of ecological landscape scenic quality evaluation model would provide important landscape quality evaluation method for the evaluation of the ecological and scenic forest.(5)In the model of spring landscape flower,the main gene and the order of the influence to the landscape quality is green ratio>non impact factor>gray intensity ratio>color layout>change of canopy layer.And the model of non flower landscape consisted of the 4 genes:green ratio>canopy character>other gene>character of life-form.In this 4 genes,the largest proportion is green ratio, the least is the character of life-form,in the summer landscape,the main gene and the order of the influence to the landscape quality consisted of the 4 genes:trunk definition,canopy shape,diseases and insect pests,tree species composition,because summer is the frequently-occurring stage of diseases and insect pests,we should know the strength of anti-diseases and insect pests of this kind of landscape forest when it is planted.In the model of autumn landscape the main gene and the order of the influence to the landscape quality is view color>sky ratio>other influence gene>distributing of leaves and fruits,>defoliate or not;And in the model of forest's inner scenery,the main gene and the order of the influence to the landscape quality is tree's shape>undergrowth coverage>canopy density>dead and fallen wood>bark color>undergrowth height.(6)Through analysis,the model of summer landscape obtained by research is suitable for xianyueshan eco-landscape forest that located in Xiamen.By analyzing model evaluation and present situation of forest,we can see that tree species structure is comparatively single and foliage plant is the main body of landscape quality,meanwhile green is the main color so the seasonal aspect is lack of changes.From eco-environmental stability the eco-landscape forest is relatively insignificant and the landscape quality is not abundant.As an important rest space,it should be based on ecology and follow some principles,such as implement step by step,classification manage ment,seasonal aspect,through these methods,we can protect the present vegetation and bring ecological function to full play.At the same time it can built multi-level forest,strengthen the landscape quality,increase species diversity,improve ecosystem stability,enrich people's visual enjoyment and realize the transformation of xianyueshan eco-landscape forest.
