Study On The Sustainable Development Of Tea Industry In Anxi County,FuJian Province

Anxi County is a typical representative and successful example of mountain tea plantation and studying the situation of Anxi County's tea plantation industry sustainable development systematically is significant to future development of our national tea industry economy.Meanwhile,the managerial measures to Anxi's tea plantation industry can be used as a reference in regional economy green development and ecological civilization construction.Based on the approach of multi-step classification,the study analyzed remote sensing images of Anxi County in the year of 1998,1999,2006,2007,2010 and 2016,analyzed the trend for expansion of tea territory within studied area in different periods.The study evaluated soil erosion degree,water footprint and landscape pattern in six research years by using the RUSLE model,CROPWAT and FragStats4.2 software respectively.At last,the study constructed the sustainable development index system with the principal component analysis to quantify the sustainable development situation of tea plantation in Anxi county.The main conclusions of this study are as follows:(1)Tea plantation areas in Anxi County indicated an obvious tendency of gradual rise in three stages,which were from 1991 to 1999,1999 to 2007 and 2007 to 2016.In general,the tea planting area of Anxi county were slow change type.According to the results of Ca-Markov prediction,the tea planting area of Anxi county will be moved from the east and the north to the southwest,some scattered tea gardens will accumulate and translate to the ecological tea garden.(2)The landscape of Anxi County was in a higher level of fragmentation,and it became further diversified and complicated,meanwhile the patch structure became more simple Landscape changes from the natural landscape to the artificial landscape,the overall landscape pattern evolution of Anxi county is the result of the interaction of human driving forces and natural driving forces.(3)Northern and southeast area of Anxi County suffered severe and even more intensified soil erosion.In recent years,less precipitation in Anxi County and soil erosion treatment measures in tea plantation promoted vigorously by Anxi County Government are the two main reasons that effectively prevented the soil erosion in tea plantation areas of Anxi County.(4)The water footprint growth of tea plantation in Anxi county was obvious.It increased from 14.714 million cubic meters in 1998 to 53.573 cubic meters in 2016.The development of tea plantation in Anxi county belonged to the coarse growth mode,on the other hand,it comes down to the unreasonable utilization of water resources.(5)Through the index construction and analysis and research,the tea plantation industry in Anxi county was sustainable development.In the past few research years,the overall score has been improving.But from the score change of the subsystem,we can see that the future development of tea planting should pay more attention to the environmental impact,and implement sustainable development.
