中文摘要:以遥感和DEM数据为基本信息源,基于网格采样研究方法,利用动态度模型分析土地利用空间异质性规律,并从集水小区角度出发研究土地利用空间自相关格局。结果表明:挠力河流域土地利用变化呈现明显的阶段性,1990—2002年耕地面积增幅最大,且以水田增加为主,2002—2014年整体面积变化趋于缓和;1990—2002年土地利用变化剧烈程度显著强于2002—2014年,前后以趋缓为主,加剧区域较少;流域不同方向上动态度均具有较好的拟合趋势,不同时间段拟合趋势差异大,但基本保持东北方向变化剧烈程度强于西南方向的态势;1990—2002年,各集水小区动态度呈现明显的高—高型和低—低型集聚趋势,空间自相关关系显著,2002—2014年,高—高型数量显著减少,且多为旱地水田化发生区,动态度集聚性变差,差异逐渐趋于缓和,未来应根据集水小区的空间自相关格局进行土地利用开发管理,应重点关注高—高型土地利用问题,适当挖掘低—低型开发潜力,对高—低型进行开发控制,对低—高型进行重点开发引导。

Abstract:Since early 1990s, the agricultural structure of Naoli River Basin had been greatly adjusted with large amounts of dry land changed into paddy field. As one of the important reclamation farms in China, the land use was changed severely in Naoli River Basin and such phenomenon would lead to a set of problems in the utilization. To reveal the spatial regular pattern and the difference of land use change in Naoli River Basin, the land use dynamic changes were analyzed, and the land use dynamic degree of the cultivated land was calculated by modeling all land use types of cultivated land and using the contribution results which was borrowed from the thought of landscape ecology, the analysis of land use spatial autocorrelation patterns was also achieved based on sub basin of Naoli River Basin. The remote sensing image data and DEM data were used as fundamental data resources. Results showed that the land use changes in the Naoli River Basin were incredibly violent, the increase of farmland area was the largest, and the internal transformations between the paddy field and dry land were the primary change. From 1990 to 2002, the change of paddy field was the main change types and the dynamic degree of land use change was obviously stronger than that during the period from 2002 to 2014. The middle and northern parts of Naoli River Basin were the mainly concentrated region of high land use dynamic degree, and the overall changing speed of the river basin was slowly trending down. The dynamic degree of land use change in different directions had good fitting trend and differed obviously between the two periods, but it maintained the basic trend that the change in the northeast direction was significantly higher than that in the southwest direction. The whole catchment previously showed the trend of aggregation of high to high and low to low obviously, the land use spatial autocorrelation patterns showed significant correlation, but in the later stage, the aggregation trend was gradually slowed down, and its aggregate on features was high to high and low to low, there was no catchment with aggregation trend of high to low. The research results can be used as references and consultancies for the land use zoning management and precise agriculture in the Naoli River Basin.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
