摘要:

农户是耕地最主要的经营主体,基于农户视角构建耕地细碎化程度评价指标体系更为合理。本文选取湖北省“江夏区—咸安区—通山县”作为研究区域,采用改进的TOPSIS法,利用农户问卷调查数据,对耕地细碎化程度评价进行了实证研究。结果表明:①耕地细碎化程度衡量指标的选取应基于耕地细碎化的属性特征,从农户微观视角,选取地块平均面积、地块数量、地块间的平均距离3个指标,衡量某一区域的耕地细碎化程度;②耕地细碎化在岗地平原地区与低山丘陵地区间存在显著差异,岗地平原地区的耕地细碎化程度低于低山丘陵地区;③研究区域地形地貌呈现出“北部岗地平原—南部低山丘陵”的分布特征,耕地细碎化的综合程度基本上呈现出“北部低—南部高”的分布规律;④在不同经济发展水平地区耕地细碎化存在显著差异,在岗地平原地区,经济发展水平越高的地区,耕地细碎化程度越高;而在低山丘陵地区,经济发展水平越高的地区,耕地细碎化程度越低。

Abstract:

Farmers are the most important actors of economic activities and the most basic decision-making units in rural China and the main managers of cultivated land, and therefore it is important to examine cultivated land fragmentation degree based on farmers' perspective. This study used average distance between parcels to characterize the spatial distribution of parcels, and developed an evaluation indicator system of cultivated land fragmentation degree. Taking Jiangxia District, Xian'an District, and Tongshan County in Hubei Province as cases, the improved TOPSIS method was employed to evaluate cultivated land fragmentation degree based on data from a farming household sampling survey. The results are as follows. (1) Selection of indicators of cultivated land fragmentation should be based on the characteristics of cultivated land fragmentation, that is, the area, number, and distribution of land parcels. Therefore, average area of parcels, number of parcels, and average distance between parcels were selected to measure the degree of cultivated land fragmentation. (2) There were significant differences in cultivated land fragmentation between hillock and plain area and low mountain and hilly area. The average area of parcels in the hillock and plain area in the north of the study area was larger than that in the low mountain and hilly area in the south. The number of parcels in the hillock and plain area was more than that in the low mountain and hilly area; the average distance between parcels or the average distance from parcels to home in the hillock and plain area was shorter than that in the low mountain and hilly area; and cultivated land fragmentation degree in the hillock and plain area was lower than that in the low mountain and hilly area. (3) Due to the difference in landform in the study area, cultivated land fragmentation degree showed a general pattern of low in the northern hillock and plain area and high in the southern low mountain and hilly area. (4) Cultivated land fragmentation showed significant differences in areas with different economic development level. In the hillock and plain area, the higher the level of economic development of the area, the higher the degree of cultivated land fragmentation; while in the low mountain and hilly area, the higher the level of economic development of the area, the lower the degree of cultivated land fragmentation.
