Analysis Of The Plough Potential Of Cultivated Land Reserve Resources Based On ARCGIS

By the end of 2010, "Eleventh Five-Year" plan outline requirements, the national arable land must not be less than 18 million acres. At the end of 2013, the second national land survey data show that China's total cultivated area has reached 135.385 million hm2, the first national land survey data is more than the nearly 13, 587,000 hm2, but in fact, there was "an area without increasing the data increase "phenomenon. "Eleventh Five-Year" plan outline requirements, by the end of 2010, the national arable land must not be less than 18 million acres. At the end of 2013, the second national land survey data show that China's total cultivated area has reached 135.385 million hm2, the first national land survey data is more than the nearly 13,587,000 hm2, but in fact, there was "an area without increasing the data increase "phenomenon. April 2014, the General Office of Land and Resources issued the "on reserve resources to carry out the investigation and evaluation of arable land in the notification", which the investigation and evaluation of arable land reserve resources to the second national land survey results based on all areas. The country's arable land reserve resources surveys, the basic situation of the various types of statistics Farmland Reserve quantity and distribution of resources, the use of the latest evaluation data aggregated to establish the investigation and evaluation of arable land reserve resources database, combined with social, economic and environmental impacts, suitable cultivated land reserve resources assessment, analysis of arable land reserve resources under different land use patterns, the development and utilization of the feasibility and timing. However, under the premise of this reality and policy, China's arable land reserve resources for the evaluation system and method also is no uniform standard. Support innovation theory; With the high-tech and research theory and experience continuously enriched, should be based on the characteristics of arable land reserve resources, from the use of high technology requires improved evaluation system; further enrich the Reserve Resources of Cultivated Land aspect Calculation model.As of this writing, a time when arable land reserve resources nationwide survey work opportunity, from the evaluation of arable land reserve resources background, research situation to start; a clear purpose and significance of research, concepts; to Tongliao Repart as the study area investigation; to each index for arable potential arable land reserve resources selected based on analysis, the establishment of arable land reserve resources potential tilth index system should be evaluated; ARCGIS space to stack with features such as mapping tools, the use of estimates of potential rating quantitative methods for the study of the county's arable land reserve resources of potential arable grades and types, and to further analyze the potential of different grades in the feature space layout. Eventually, according to the potential rating should tilth and structure and layout, put forward reasonable suggestions on the development of the county's arable land reserve resources.From the theoretical sense, this paper discusses the research system, can enrich the arable land reserve resources development and utilization in the theoretical study of specific methods, research ideas, and other aspects of the selection of indicators; from a practical sense, the results of this study open for Kailu County arable land reserve resources in the study area has strong applicability and guidance for Kailu arable land reserve resources development and utilization of the reference recommendations.
