Study on Temporal-Spatial Distribution of Cultivated Land Utilization Potential in Dalate Banner and Its Limiting Factors
摘要
Abstract
Cultivated land utilization potential is the gap between theoretical, realizable and actual ca-pacities.The researches on its temporal and spatial distribution and influencing factors are of great significance for ramp-up of arable land production capacity in the western ecological fragile areas and food security main-tenance.Based on the results of agricultural land production calculation and field survey of arable land quality monitoring from 2009 to 2011, the temporal-spatial distribution of different levels’ arable land utilization po-tential in Dalate Banner and its limiting factors were studied by stepwise regression.The total theoretical utili-zation potential in Jigesitai Town was the minimum, while that in Zhaojun Town was the highest, which showed widening trend in the study.The spatial distribution pattern of realizable utilization potential showed higher in the north and west, but lower in the south and east.The Town with the minimum and the highest realizable u-tilization potential was Zhandanzhaosumu and Zhaojun Town respectively, which showed narrowing trend.Four major limiting factors of arable land theoretical utilization potential for Dalate Banner were irrigation time, wa-ter source, erosion and pollution situation.Seven major limiting factors of the realizable utilization potential were actual yield, topography, severe weather, irrigation water source, structure of soil profiles, mechanical input and irrigation method.关键词
