中文摘要:
      以晋江市为研究区,基于2016年土地利用现状数据选取斑块面积指数、斑块形状指数和斑块分散指数3个景观指数构建耕地细碎化指标体系,从不同尺度对就地城镇化下晋江市耕地细碎化程度和空间分布进行了评价,然后基于耕地细碎化空间自相关特征并结合地理加权回归模型和地理探测器方法分析不同因素对耕地细碎化的影响。结果表明:(1)晋江市耕地细碎化整体处于中度细碎化水平,其全局莫兰指数为0.3827,具有一定的空间正相关,呈现出明显的空间集聚现象。(2)高程、坡度和河流对耕地细碎化影响度以正影响为主,居民点和交通以负影响为主,土地利用类型中建设用地对耕地细碎化影响最为突出。细碎化高集聚区域基本处在各因素的主要影响度范围内,各个因素对耕地细碎化空间集聚产生显著影响。(3)在选取的因素中自然因素(高程、坡度和河流)和人类干扰因子(居民点、交通和土地利用类型)对耕地细碎化的空间分异影响显著不同,自然因素(高程、坡度和河流)是晋江市耕地细碎化的主要原因,且居民点与自然要素共同作用会加剧耕地细碎化程度。
英文摘要:
      Jinjiang City was used as the research area, based on the current land use data in 2016, cultivated land fragmentation index system was constructed to evaluate the degree and spatial distribution of cultivated land fragmentation in Jinjiang City under in-situ urbanization from different scales through three landscape indexes: patch area index, patch shape index and patch dispersion index. Then,based on the spatial autocorrelation results of cultivated land fragmentation, combined with geographically weighted regression model and geodetector method, the influencing factors of cultivated land fragmentation were analyzed. The results show that: (1) The overall fragmentation of cultivated land in Jinjiang City is at a moderate level of fragmentation, with a global Moran index of 0.3827, which has a certain positive spatial correlation, showing obvious spatial agglomeration. (2) The influence of elevation, slope and rivers on the fragmentation of cultivated land is mainly positive, and residential areas and traffic are mainly negative. Among the land types, the impact of construction land on the fragmentation of cultivated land is the most prominent. Fragmentation and high agglomeration areas are basically within the main influence range of various factors, and each factor has a significant impact on the spatial agglomeration of arable land fragmentation. (3) Among the selected factors, natural factors (elevation, slope and river) and human disturbance activities (residential areas, traffic and land use types) have significantly different effects on the spatial differentiation of cultivated land fragmentation. Natural factors (elevation, slope and River) is the main reason for the fragmentation of cultivated land in Jinjiang City, and the combined effect of residential areas and natural elements will increase the degree of fragmentation of cultivated land.
