The Research Of Dali Prefecture Agro-ecological Development

The party's 18th report had incorporated ecological civilization "five in one" overall layout,and analyzed the relationship between agricultural development and ecological civilization in depth.Agriculture is the foundation of the national economy,and it is the most closely associated with the natural eco-industry,also is the basis for the construction of ecological civilization.Dali Prefecture is located the southwest in China,central west in Yunnan Province,and the terrain is complex.Its ecological protection has a very important strategic position in the national ecological construction.The paper,according to the concept of ecological civilization,and from the perspective of geography,take the all countries of Dali Prefecture for example to evaluate the development of agriculture ecological,using the Delphi method,entropy method,AHP,multiple regression analysis,arcGIS and so on.Based on the structures of agriculture sector,technological and spatial in three dimensions,the paper analyze the development of agro-ecological in Dali Prefecture further.Finally,the paper throw out some suggestions from adjusting agricultural structure,innovativing technologies and optimizing the spatial structure of agriculture to in line with Dali Prefecture agro-ecological development.The paper draw the following conclusions by studying the development agro-ecological in Dali Prefecture:1.Dali Prefecture has excellent conditions to develop ecological agriculture.Dali Prefecture has sorts of natural conditions,for example,excellent climate,light,water etc.and social conditions,for example,the improving economic,science technology etc.to supported the development of ecological agriculture.But faced with environmental stress and the pollutions of agricultural nonpoint source.2.The results of Dali Prefecture agro-ecological comprehensive evaluation.The evaluation results show that,on the whole,the better natural conditions for agriculture,and the less degree of human intervention,then the higher agricultural output.Also,the worse natural conditions for agriculture,and the more serious degree of human intervention,then the less agricultural output.Specifically,Binchuan County,Dali City and other four counties because of better natural conditions for agriculture,and less degree of human intervention,higher higher agricultural output,develop agro-ecological better,other 6 counties,for instance,Eryuan County,Midu County and so on,due to poor natural conditions for agriculture,less degree of human intervention,lower agricultural output,develop agro-eco logical worse.Binchuan is the highest evaluation score(0.719),and Jianchuan is the lowest evaluation score(0.526),the former score is higher 25.8%than the average of Dali Prefecture,and the latter is lower 8%than the average,the difference is 0.193.3.The characteristics of agriculture structure of agro-ecological in Dali Prefecture development.Dali Prefecture agricultural structure mainly dominated by crop farming,supplemented by animal husbandry,and forestry,fisheries and forestry,animal husbandry proportion fishery service are small.In general,farming and forestry contributed more to the development of ecological agriculture,and animal husbandry,forestry,fisheries and forestry,animal husbandry proportion fishery service contributed less.Specifically,the Dali Prefecture farming average contribution rate is 88.88%,5 counties(Jianchuan County,Binchuan County etc.)are above average,7 counties(Midu County,Dali City etc.)are below average.Jianchuan County is the most highest,which higher than the average of 9.46%,the lowest Yunlong County is less than the average of 7.46%,the difference is 16.92%.The difference is large,Dali Prefecture planting development have a big difference.Forestry,animal husbandry and fishery are little difference,respectively,10.90%,7.47%,6.79%,1.53%.4.The characteristics of structure of agricultural technology of Dali Prefecture agro-ecological development.The structure of agricultural technology in Dali Prefecture are mainly biotechnology-based,and supplemented by mechanical techno logy.Overall,Dali Prefecture agricultural technology is balanced(except Dali City).In detail,Dali County biotechnology average contribution rate is 72.05%.Midu County is the highest,which is higher than average of 7.99%with biotechnology contribution rate for 80.04%,and Dali city is the lowest,which is lower than the average of 20.79%,the difference is 28.78%.The technical structure of Dali Prefecture average contribution rate is 27.95%,Dali City is the highest whose contribution rate is 48.74%,which higher than the average of 20.79%.Midu County is the lowest whose contribution rate is 19.06%,which is lower than the average of 7.99%,and the difference is 28.78%.5.The characteristics of spatial structure of agro-ecological development in Dali Prefecture.Dali Prefecture agro-ecological spatial layout display that,on the whole,the spatial structure of agricultural ecological development in Dali Prefecture show that the high and low values concentrated in together respectively,and the high value distributed in the southeast,and the low value distributed in the northwest.In particular,Binchuan County,Dali City and other 6countries distribute mainly in the southeastern with better ecological development and higher contribution rate.Er'yuan,Yongping County and other 6countries distribute mainly in the northwestern with poor ecological development and lower contribution rates.Only Midu located in the southeast.6.The suggestions for Dali Prefecture agro-ecological development.Regarding for the analysis of Dali Prefecture agro-ecological structure,the paper proposed from agricultural sectoral structure,technical structure and spatial structure.First,adjust the internal structure of the agricultural industry,and develop featured agriculture adapting to circumstances.Second,promote to establish ecological-suitable agricultural techniques.Third,optimize distribution of ecological agriculture.Fourth,strengthen the control of agricultural nonpoint source pollution and protect agricultural-used land.Five,develop pollution-free,green and organic food certification.
