【摘要】：耕地是土地资源中最珍贵的资源,人多地少的基本国情导致保护耕地的压力不断增大。保护耕地基本从数量稳定及质量提升两方面入手,进行高标准农田建设是保护耕地数量与质量最直接且最有效的办法。萝北县拥有丰富土地资源,具备建设高标准农田的条件,积极抓住建设现代农业示范县这一政策支持,加快进行高标准农田建设是发展的必然选择。因此,针对萝北县展开高标准农田建设研究,可以为当地进行高标准农田建设提供科学依据及理论支撑,更具现实意义。由于萝北县辖区内森工林场、国营农场及县属乡镇对土地资源的需求及要求不尽相同,进行土地资源评价及高标准农田建设评价的标准并不能达到统一,因此,本文选取萝北县县属5镇3乡65个行政村为研究区,以“确定建设区域—分析建设时序安排—提出建设措施”为主要的建设路径,通过分析研究区内建设条件要素的现状及进行建设适宜性评价,确定研究区内可建设区域,并以建设适宜性评价结果为主导进行高标准农田建设时序安排,通过障碍度模型诊断主要障碍因素并对不同时期内障碍因素进行排序,提出可行性的建设措施。研究结果表明:1)综合自然条件要素分析及建设适宜性评价结果,依据高标准农田可建设区域的准则即高标准农田可建设区域为除影响因素不可改造区及不适宜建设区以外的区域,萝北县高标准农田可建设区为除坡度25°以外的所有区域,总面积为74301.27 hm2。2)将研究区内可建设区域与高标准农田适宜性评价结果进行叠加分析,得到该区域高标准农田的建设时序安排,分为近期建设区、中期建设区及远期建设区。其中,近期建设区面积为20834.59 hm2,其面积百分比为28.04%,其主要分布于团结镇东南部、东明朝鲜族乡西北部、凤翔镇南部、肇兴镇西部及鹤北镇东部地区;中期建设区面积较大为41149.24 hm2,所占比例为55.38%,其分布在整个可建设区域内,其中团结镇面积较大,其他乡镇分布比例在1.50%~8.50%之间,是该区域主要建设地区;远期建设区主要分布在名山镇和鹤北镇北部,其他乡镇边界处有少量分布,且在各乡镇所占比例相对较小,区域面积最小为12317.44 hm2,比例为16.58%。3)通过障碍度模型,高标准农田建设主要障碍因素包括沟渠密度、路网密度、林网密度、道路通达度、乡镇影响度、耕作便利度及田块集中连片度,要素在不同建设时期内影响程度不同导致其建设顺序不同。针对影响因素提出灌溉工程、田间道路建设工程、农林防护工程及土地平整工程四个建设工程措施,并建议依据障碍度总值越高贡献率越大的指标对高标准农田建设影响越大、越应优先建设的原则,不同建设时期应根据障碍因素的排序进行先后建设。
[Abstract]:Cultivated land is the most precious resource in land resources. The basic national conditions with large population and less land lead to increasing pressure to protect cultivated land. The protection of cultivated land basically starts from two aspects: quantity stability and quality improvement. The construction of high standard farmland is the most direct and effective way to protect the quantity and quality of cultivated land. Luobei County has abundant land resources, has the conditions to construct high standard farmland, and actively grasps the policy support of constructing modern agricultural demonstration county. Speeding up the construction of high standard farmland is an inevitable choice for development. Therefore, the research on the construction of high standard farmland in Luobei County can provide scientific basis and theoretical support for the construction of high standard farmland. Because of the different demands and requirements for land resources in the forest farm of Luobei County, state-owned farms and counties and townships, the standards for land resources evaluation and high standard farmland construction evaluation are not uniform. In this paper, 65 administrative villages in 5 towns and 3 townships in Luobei County are selected as the research areas, and the main construction path is "determining the construction area, analyzing the construction timing arrangement and proposing construction measures". Based on the analysis of the present situation of the construction conditions and the evaluation of the construction suitability in the study area, the construction area in the study area is determined, and the timing arrangement of the high standard farmland construction is carried out with the result of the construction suitability evaluation as the leading factor. By using the obstacle degree model to diagnose the main obstacle factors and to rank the obstacle factors in different periods, the feasible construction measures are put forward. The research results show that: 1) synthesizing the analysis of natural condition elements and the evaluation results of construction suitability. According to the criterion of the high standard farmland construction area, that is, the high standard farmland construction area is the area except the influence factor and the unsuitable construction area, and the high standard farmland construction area in Luobei County is all the regions except the slope of 25 掳. The total area is 74301.27 hm ~ (2. 2)) the results of the evaluation of the suitability of the construction area and the high standard farmland in the study area are superimposed and analyzed, and the construction schedule of the high standard farmland in this area is obtained, which can be divided into the short-term construction area, the medium-term construction area and the long-term construction area. The area of recent construction area is 20834.59 hm ~ 2, its area percentage is 28.04. It is mainly distributed in the southeast of Tuanjie, the northwest of Dongming Korean nationality, the south of Fengxiang, the west of Zhaoxing and the east of Hebei. The area of middle construction area is 41149.24 hm2, the proportion is 55.38, it is distributed in the whole buildable area, the area of Tuanjiezhen is larger, the distribution of other villages and towns is between 1.50hm-2 and 8.50%, which is the main construction area in this region. The forward construction area is mainly distributed in the north of Mingshan Town and Hebei Town, and there is a little distribution at the boundary of other towns and towns, and the proportion in each township is relatively small. The minimum area is 12317.44 hm2, the proportion is 16.58. 3) the barrier degree model is adopted. The main obstacles to the construction of high standard farmland include channel density, road network density, forest network density, road accessibility, township impact, farming convenience and field concentration. The influence degree of factors in different construction period leads to different construction order. Four construction measures, irrigation engineering, field road construction project, agriculture and forestry protection project and land leveling project, are put forward in view of the influence factors. It is suggested that the higher the total obstacle value the greater the contribution rate, the greater the impact on the construction of high standard farmland, and the more priority should be given to construction, and the construction should be carried out according to the order of obstacle factors in different construction periods.
