Analysis of spatio-temporal variation characteristics of cotton planted areas in Weigan -Kuqa River Delta Oasis
摘要
Abstract
Using the relevant statistical data of cotton planted area and yield in study region ,has explored the spa-tio-temporal variation characteristics of cotton planted areas with yield and effect of the function of yield and area to the cotton output .The research results showed that :(1 ) In recent 62 years ,the cotton planted area ,cotton output and yield total have showed an upward trend in the study region ,further more ,have performed obvious stage and fluctuation ,slow increase from 1949 to 1985 ,but rapid growth from 1986 to 2011 .(2 ) As to the cotton production fluctuation ,the effect of the unit yield was 42 .04% ,the area was 50 .96% .During 1949 to 1985 ,the unit yield increase was more contribu-tion to the cotton output increasing ,while the cotton planted area was more contribution to the cotton output increasing during 1986-2011 .(3) Before 1985 ,the cotton planted area was rather stable with less fluctuation ,mostly expanded by the area of food crop ,but after 1986 ,cotton planted area begun to expand rapidly ,most by wasteland reclamation . (4 ) The fluctuation of the cotton market price ,the rise of the production cost ,the cotton output up and down ,degrada-tion of production environment and the cotton variety and so on had a direct impact to the competitiveness of cotton pro-duction and the income increasing of cotton farmers in the study area .关键词
