【摘要】：近年来,随着神木县煤炭产业的飞速发展,县域经济呈跨越式增长,带动了神木县各项事业的蓬勃发展。在此背景下,神木县土地资源发生了较大变化,建设用地供不应求,废弃工矿用地处于闲置状态,耕地资源总量大幅下降等等;盲目开发土地资源给原本脆弱的生态环境带来的负面影响也是显而易见的。所以,要缓解神木县用地矛盾、有效增加耕地面积、提高粮食产量、改善生态环境,必须对神木县的耕地后备资源进行分析评价。关于耕地后备资源的开发利用,既要保证数量,更要保证质量,还要合理安排。因此在摸清耕地后备资源总量的基础上,有必要对耕地后备资源开发时序进行专项研究,这对于后期科学、有序的组织耕地后备资源开发利用工作、调整和优化土地利用结构、制定合理的土地整理规划具有重要的现实意义。本文主要研究内容和成果有以下两个方面:(1)采用“限制性因子”评价法对神木县耕地后备资源的宜耕性进行分析评价,结果表明神木县宜耕后备资源区域分布差异大。位于县境北部沙漠草滩区的宜耕后备资源潜力占全县总面积的78.17%;位于县境中部丘陵沟壑区的宜耕后备资源潜力占全县总面积的7.25%;位于县境东南部土石山区的宜耕后备资源潜力面积占全县总面积的14.58%。(2)从关乎耕地后备资源开发的自然优势度、经济支持度、社会接受度三大方面构建耕地后备资源开发时序评价指标体系,研究神木县耕地后备资源开发时序。根据评价分值的大小确定耕地后备资源的开发时序,得分越大越接近1,开发时序越靠前,得分越小越接近0,开发时序越推后。经评价后,确定神木县耕地后备资源开发主要受自然优势度的影响,受经济支持度和社会接受度的影响相对较小。
[Abstract]:In recent years, with the rapid development of the coal industry in Shenmu county, county economy leaping growth, driven by booming Shenmu undertakings. Under this background, changes of land resources in Shenmu county, construction land supply, abandoned industrial land in idle state, the total amount of cultivated land resources declined sharply negative and so on; influence of the blind development of land resources brought to the fragile ecological environment is obviously. So, in order to alleviate the Shenmu land conflicts, effectively increase the cultivated area, increase food production, improve the ecological environment, to analysis and evaluation of reserve resources of cultivated land in Shenmu county. Development and utilization of arable land reserve resources, both to ensure the number, but also to ensure the quality, but also reasonable arrangements. So based on the total amount of arable land reserve resources to find out, it is necessary to reserve land resource development special time This study, for the latter part of science, development and utilization of cultivated land resources organization work orderly, adjust and optimize the structure of land use, reasonable land consolidation planning has important practical significance. In this paper, the main research contents and results are the following two aspects: (1) suitability by "limiting factor" evaluation method of Shenmu county land reserve resources are evaluated. Results show that the difference of regional distribution of Shenmu arable reserve resources. County is located in the northern desert marsh area of arable reserve resources potential of total area of the county accounted for 78.17%; county is located in the territory of the Middle Hilly Region of arable reserve resources potential accounted for 7.25% of the total area of the county is located in the southeast; Department of mountainous area of arable area reserve resources potential of the county's total area of 14.58%. (2) from the related land reserve resources development natural advantage, economic support, social acceptance To construct the evaluation index system of cultivated land reserve resources development series three aspects of Shenmu county land reserve resources development. According to the temporal development of sequential evaluation score to determine the size of arable land reserve resources, the bigger the score is close to 1, the development of sequential front, the smaller score closer to 0, the more push. The development of sequential evaluation. To determine the effect of the development of reserve resources of cultivated land in Shenmu county is mainly affected by the natural advantage degree, economic support and social acceptance of a relatively small impact.
