Research On Campus Landscape Optimization Of Shenyang Agricultural University Based On Deep Ecology Theory

With the rapid development of the global economy,the acceleration of industrialization and urbanization,the harm to the ecological environment is also increasing.Facing with these problems,we should actively look for methods which is effective and feasible enough to restore and protect the ecological environment.We all know that the college campuses play an important role in the city,and as a subsystem of urban green space,it can not only help to restore the urban ecosystem,but also help to strengthen human ecological education and cultivate ecological awareness.After deeply knowing the core idea of ecology,I think college campuses are suitable for prioritizing research in this area.Therefore,this paper attempts to use deep ecological theory and combine it with landscape ecology,which may be used as the guiding direction of university ecological planning and applied to the study of campus ecological planning.The article mainly takes Shenyang Agricultural University as the research object and uses the PSR model which reflects the relationship between people and the environment.The research result is based on several indicators,five of which are about environmental pressure,eight environmental status and six social response.Besides,it combines landscape pattern index,satisfaction survey,spatial syntax and other methods to analyze the landscape pattern of Shenyang Agricultural University and conduct ecological health assessment.On the basis of dividing the campus into three districts,the author select a better landscape pattern state through comparative analysis of ecological health evaluation results.The ecosystem service function is one of the necessary conditions for the sustainable development of the ecosystem like ecological health.Therefore,the paper uses the equivalent factor method to estimate the value of the ecosystem service function of the campus of Shenyang Agricultural University.Through the integrative study of ecological health and ecosystem service function,the author draws several conclusions,which are mainly shown as follows:Through the above method,the largest area of Shenyang Agricultural University is the green land patch,the landscape diversity value is(1.4009),the overall landscape pattern diversity is very good,the campus landscape land use is relatively rich;the fractal dimension is(1.6011),the value is slightly higher than the median value of the threshold of the index,which indicates the shape of each patch in the landscape is more complicated.The landscape connectivity(92.8802)indicates that the connectivity between landscape patches in Shenyang Agricultural University is high.The landscape uniformity index of(0.8704)indicates thatthere is no obvious dominant type of campus landscape.The degree of landscape fragmentation(20.2375)and the degree of separation(59.1254)indicate that the landscape patches are relatively fragmented and complexly distributed.The author use The AHP Analytic Hierarchy Process to determine the weight of each index,and take the efficacy coefficient method to dimensionless processing the index.The final ecological health score of Shenyang Agricultural University was 61.6459.According to the ecosystem health classification standard,it can be known that the ecosystem of Shenyang Agricultural University is at a healthy level.It shows that the overall ecosystem structure is reasonable and the ecosystem is stable,and there are basically no ecological anomalies.We can see the human response is fine,and it can still achieve a sustainable development state in harmony with nature.At the same time,the three districts of the campus were compared and ranked as South Campus(60.6323)> North Campus(59.6005)> Experimental Area(58.1482),and the ecological structure of South Campus was found to be better.Based on the equivalent factor method,the value of the ecosystem service function of Shenyang Agricultural University in 2017 was 115.9792 × 106 yuan.Taking the largest area of green space patches as the source and using least-cost path method to obtain the cumulative resistance surface through the GIS software,we can calculate and analyze the related data and then generate potential corridors of Shenyang Agricultural University and ecological corridor optimization maps.These research results may provide optimization suggestions for the ecological network of Shenyang Agricultural University and strengthen the links between ecosystem patches in Shenyang Agricultural University.And it also can alleviate the degree of landscape fragmentation and enhance the ecosystem stability.In addition,it is suggested that we can enrich the level of plant communities according to the characteristics of waterfront landscape plant configuration,and consider the role plants plays in purifying water.Finally,we can combine the historical and cultural connotation of the campus to create a beautiful and characteristic waterfront landscape of agricultural universities.
