    摘要:

    利用2013—2015年土地變更調查新增耕地數據,,基于縣域和區(qū)域兩種尺度,,運用重心模型、區(qū)位基尼系數,、地理集中度以及統(tǒng)計分析等方法,,分析3年京津冀地區(qū)新增耕地時空特征,并從不同來源對新增耕地狀況進行深入解析,,以期為京津冀后續(xù)建設尤其是雄安新區(qū)建設提供參考,。研究結果表明:從2013—2015年京津冀新增耕地整體看,新增耕地主要集中在中東部平原區(qū),、西部山區(qū)和北部高原區(qū)3大區(qū)域,;從不同年份分析,京津冀地區(qū)新增耕地面積先減后增,,重心從京津冀東北方逐漸向西南方偏移,,并呈高度聚集態(tài)勢,。新增水澆地是京津冀地區(qū)新增耕地的主要地類。新增耕地主要是通過農村土地整治新增耕地的方式而來,,大部分來源于草地,,生態(tài)問題愈發(fā)突出。最后,,深入分析新增耕地時空變化規(guī)律,,建議京津冀在未來建設中因地制宜,加大〖JP〗節(jié)水力度,,注重生態(tài)文明建設。

    Abstract:

    Based on the data of newly increased cultivated land from 2013 to 2015 at the district and countylevel in Beijing-Tianjin-Hebei region, the whole feature of the newly increased cultivated land, the feature of different types newly increased cultivated land were explored, and the newly increased cultivated land was analyzed from the perspective of different sources indepth. The research methods included gravity center model, Ginicoefficient, geographic concentration and some methods of statistical analysis. Research results showed that from 2013 to 2015, all of the new cultivated land in the Beijing-Tianjin-Hebei region was mainly concentrated in the middle east plain, western mountainous areas and the northern plateau areas. Analyzing the newly increased cultivated land in different years, the area of the newly increased cultivated land in Beijing-Tianjin-Hebei region was decreased first and then increased;the gravity center was transferred from northeast to southwest. And the newly cultivated land was highly concentrated. Gry land was mainly cultivated land types in Beijing-Tianjin-Hebei region, but the newly increased irrigated land was mainly newly increased cultivated land type. The largest proportion was land consolidation’s newly increased cultivated land in rural. The main source of the newly increased cultivated land was grassland, so that ecological problems were becoming more prominent. On this basis, reasonable suggestions were put forward for Beijing-Tianjin-Hebei region in the future land remediation work. It was suggested that the Beijing-Tianjin-Hebei project should adjust measures to local conditions in the future, increase water efficiency, and pay attention to the construction of ecological civilization.
