摘要
根据对新疆生产建设兵团某团三连2007年与2008年棉田调查,对两年的生产投入、生产效率进行了空间对比,发现93.6%的田块投入减少;投入增加的棉田分散于各个方位,但多为交通中等通达区位;投入率减少程度较大的田块多分布在林带旁。生产效率上处于耕地外围边缘的田块呈高度增长;生产效率变化率成负的田块多离居住区较近或处于耕地边缘;生产效率变化率中等的农田占总数的44.87%,且连片集中分布;无论正向高变化率还是负向高变化率整体上呈分散状态。究其原因,制度的变革降低了棉花生产的投入成本,提高了田间管理效率,并促使职工对区位较差田块的重视。此外,职工对制度变革的态度在相当程度上也影响着农田生产效率,进而影响了棉花生产效率的空间分布。
Based on input and output survey data of cotton field in the third company in one corps of Xinjiang production and construction in 2007 and 2008, the spatial contrast was made on investment and productivity. In terms of investment, firstly,93.6% of fields were decreased in 2008. Secondly, the fields increase in investment spread in all orientation. From the point of traffic in the company, they have medium accessibility, means medium remote from residential district. Thirdly, the fields having higher rate of reduce in investment most spread near forest belt. Spatial signature on production efficiency indicates： firstly, the fields at the out-edges of farmland have sharply increase in productivity in 2007 compare with 2008＇s.Secondly, the fields which have negative rate of change most nearby residential district or on the edge of farmland. Thirdly, the fields which have medium rate of change on productivity are concentrated and accounting for 44.87% .Finally, the fields whether which rate of change in productivity are positive or negative are dispersed. The main reasons are changes in the policies which reduce the input costs of cotton production, improve the efficiency of field management, and encourage workers to increase efficiency in the field of poor location.
