Analysis Of Landscape Pattern Of Leisure Agriculture In Shangyu

Agricultural landscape is an important material resource,which plays an important role in rural social,economic development and ecological environment construction.What's more,leisure agriculture is a main mode of agricultural landscape resource utilization.Taking the area of Shaoxing Shangyu as the research area to carry out the research and analysis on the landscape pattern of leisure agriculture,to understand and master the basic characteristics of regional leisure agriculture landscape pattern,and to provide scientific reference basis and technical service support for the development of leisure agriculture in Shangyu area.At first,collect the basic data materials,such as remote sensing image and digital elevation data,standard topographic map,land use current map and so on of Google Earth in the area of Shangyu in Zhejiang Province from 2010 to 2015.Through the whole scene remote sensing image processing,the research area and the regional recreational agriculture development and utilization basic situation were determined.According to the data of the Agriculture and Forestry Bureau of Shangyu area and the situation of On-the-spot survey,the visual interpretation was carried out.Then,onsite reconnaissance and adjust the vector boundary.After that the vector boundary was transformed into projection coordinates,and the spatial pattern index method of landscape ecology was adopted.According to the results of the analysis of landscape pattern index,the conclusions could be drawn as follows:(1)Characteristics of plaque in recreational agricultural park.In addition to the large patch area of the Shangyu area,the spot size of other agricultural parks was basically the same.The total area of different zones was larger,the number of plaques varied considerably,the development of the park was unbalanced,the boundary shape of agricultural park was simpler.According to the index analysis of the whole feature of the plaque,it was known that the agricultural park occupied a small proportion of the landscape area and the largest area of the agricultural park was located in the Shangan Comprehensive Park,which showed that the patch of Shangan Agricultural Comprehensive Park could better meet the construction of large-scale agricultural park in some extent.(2)Types of planting in leisure agricultural park.The number of parks and the largest number of patches were water orchards,the least of which was flower garden.The distribution of pubescens was restricted by terrain conditions,and the distribution was denser,and each patch area was larger.The distribution of recreational agricultural park with fruit as the planting type is wide,the degree of fragmentation of the landscape was relatively large,and the distribution was scattered.The fruit park was widely distributed,and the size of plaque was obviously different.The average patch shape index of tea plantation was the largest,the shape of plaque was the most irregular,besides,the landscape types had a similar ecological process and the overall landscape heterogeneity was lower.The distribution uniformity of tea garden and flower garden was poor,the superiority was lower,and it need to be further rational and scientific developed.(3)Spatio-temporal evolvement process of leisure Agricultural Park.From the perspective of space-time evolution process,the water orchard from 2010 to 100% of the total area of leisure agricultural landscape reduced to 60% in 2015,indicating that the flower nursery garden,vegetable garden,pubescens and other planting content as the main industrial park gradually built up.From2011-2015,the proportion of the total area of leisure agricultural landscape in tea garden remained unchanged,and the vegetable garden showed a slight downward trend.From the spatial distribution of landscape elements,the most obvious configuration was the pattern of reunion distribution.The leisure Agricultural park in Shangyu was transformed from star-point to large-scale development from the spatial distribution of 2010-2014,which resulted of constructing a larger scale of farmland patches or background.What's more,it was obvious that the development had been further promoted and the process of the agricultural park formation had been speed up in a certain extent.
