【摘要】：迁村并点规划是社会主义新农村建设中的一个重要部分，随着迁村并点规划的实施导致农民的耕作出行距离或时间即耕作半径发生了变化，这对于农民的耕作出行利益产生了影响。那么如何在迁村并点规划获得集聚效应的同时保障农民耕作出行的利益？研究此问题，对新农村建设具有的一定的理论和现实意义。论文首先分析迁村并点的时代背景和理论背景，然后分析了耕作半径五个主要制约因子对耕作半径和农村居民点布局的影响，，接着推演了合理耕作半径的计算步骤，最后运用了重庆市綦江区太公山(万兴)绿色农业休闲园区规划和四川省芦山县思延生态(有机)农业示范园控制性详细规划两个规划案例进行实证。主要研究结果如下。一是耕作半径可以成为农村居民点布局规划的研究方法之一。二是耕作半径的五个制约因子影响着耕作半径的辐射范围。首先平原到丘陵再到山地耕作半径呈现增加趋势。其次交通条件越发达耕作半径的辐射范围越大。第三机动化率越高耕作半径的距离越远。第四农业机械化率越高耕作半径的辐射范围越大。第五农用地布局集约化越高、破碎度越低则耕作半径的辐射范围越大。三是耕作半径的五个制约因子可以量化运用。量化运用可以分为两类，一类是可以对耕作半径二维图面表达时进行修正的修正型指标，包括对地形地貌进行衡量的地形位指数和对农业用地布局进行衡量的垦殖指数两个指标；另一类是可以对计算出的耕作半径提供极限参考值的参考型指标，包括对交通条件进行衡量的交通通达度、对出行方式进行衡量的机动化比率和对农业技术与装备进行衡量的耕种收综合机械化水平三个指标。四是合理耕作半径推演运用主要分为八个步骤。五是运用案例实证证明合理耕作半径的运用是有必要的。特别是在山地丘陵地区，将农村居民点集约在几个中大型农村居民点的做法是不适宜的，需要运用合理耕作半径进行控制。综上所述，运用耕作半径优化农村居民点规划布局是具有普适性的。但由于本文运用合理耕作半径优化农村居民点布局的实例有限，在后续研究中还需要运用大量的案例进行实证分析，从耕作半径的计算方法、量化指标、修正过程等方面不断完善合理耕作半径的优化方法。
[Abstract]:It is an important part in the construction of the new socialist countryside that the planning of moving villages and merging points leads to the change of farmers' travel distance or time, that is, the radius of farming, as a result of the implementation of the plan. This has had an impact on farmers' farming interests. So how to obtain the agglomeration effect in the relocation of village and point planning while protecting the interests of farmers' farming trip? The study of this problem has certain theoretical and practical significance for the construction of new countryside. Firstly, the paper analyzes the background and theoretical background of moving from village to village, then analyzes the influence of five main restriction factors of tillage radius on the farming radius and the distribution of rural settlements, and then deduces the calculation steps of reasonable farming radius. Finally, two planning cases of Taigongshan (Wanxing) Green Agricultural Leisure Park in Qijiang District of Chongqing and Siyan Ecological (Organic) Agricultural demonstration Park Control Planning in Lushan County of Sichuan Province are used to demonstrate the case. The main results are as follows. First, the tillage radius can become one of the research methods of rural settlements layout planning. The other is that the radiation range of the tillage radius is affected by the five restriction factors of the tillage radius. First of all, the radius of cultivation from plain to hill and then to mountain showed an increasing trend. Secondly, the more developed the traffic conditions, the larger the radiation range of the tillage radius. The higher the third motorization rate, the longer the distance of the tillage radius. The higher the rate of agricultural mechanization, the larger the radiation range of farming radius. The higher the intensive distribution of the fifth agricultural land, the larger the radiation range of the tillage radius is. Third, the five restriction factors of tillage radius can be used quantitatively. The quantitative application can be divided into two categories. One is a modified index that can be used to express the two-dimensional surface of the tillage radius. It includes two indexes: topographic position index to measure topographic landform and reclamation index to measure agricultural land distribution; the other is a reference index that can provide limit reference value to the calculated tillage radius. It includes three indexes: the degree of traffic accessibility, the ratio of motorization to travel mode, and the level of comprehensive mechanization of farming and income measured by agricultural technology and equipment. Fourth, the application of rational tillage radius is mainly divided into eight steps. Fifth, it is necessary to use the case to prove the rational use of farming radius. Especially in mountainous and hilly areas, it is not appropriate to concentrate the rural residential areas in several large and medium-sized rural settlements, and it is necessary to use reasonable farming radius to control them. To sum up, the use of farming radius to optimize the layout of rural residential planning is universal. However, due to the limited application of rational tillage radius to optimize the distribution of rural residential areas in this paper, a large number of cases should be used for empirical analysis in the follow-up study, from the calculation method of tillage radius, quantitative indicators, The optimization method of reasonable tillage radius has been improved continuously in the correction process.
