Examining the influence of the implementation of Major Function-oriented Zones on built-up area expansion in China

China had implemented the national strategies for Major Function-oriented Zones （MFOZs） to realize the goal of national sustainable development since 2010. This study analyzed and compared spatio-temporal characteristics and differences in built-up area for China＇s MFOZs using a China＇ s Land Use Database （CLUD） derived from high-resolution remotely sensed images in the periods of 2000-2010 and 2010-2013. To sum up： （1） The percentage of built-up area in each of the MFOZs was significantly different, revealing the gradient feature of national land development based on the distribution of the main functions. （2） Annual growth in built-up area in optimal development zones （ODZs） decreased signifi- cantly during 2010-2013 compared with the period 2000-2010, while annual growth in built-up area in key development zones （KDZs）, agricultural production zones （APZs） and key ecological function zones （KEFZs） increased significantly. （3） In ODZs, the average annual increase in built-up area in the Yangtze River Delta region was significantly higher than in other regions; the average area increase and rate of increase of built-up area in KDZs was faster in the western region than in other regions; average annual area growth of built-up area in APZs in the northeast, central and western regions was twice as high as the previous decade on average; the annual rate of change and increase in the dynamic degree of built-up area were most notable in KEFZs in the central region. （4） The spatial pattern and charac- teristics of built-up area expansions in the period 2010-2013 reflected the gradient feature of the plan for MFOZs. But the rate of increase locally in built-up area in ODZs, APZs and KEFZs is fast, so the effective measures must be adopted in the implementation of national and regional policies. The conclusions indicated these methods and results were meaningful for future regulation strategies in optimizing national land development in China.

面向乡村振兴战略的乡村发展格局及其分区研究

该文综合运用兴趣点、遥感影像等多源数据,基于“生产-生活-生态”(简称“三生”)空间功能视角,设计了面向乡村振兴战略的乡村发展评价方法,并以平谷区为例开展乡村发展格局及分区研究。结果表明:平谷区乡村生产、生活、生态功能的空间分布特征,总体符合平谷区生态涵养建设目标及产业发展规律。基于空间的主导功能,将平谷区划分为生产主导、生活主导、生态主导、生活生产复合、生产生态复合、生态生活复合、生产生活生态复合共7类功能区。通过分析发现,平谷区基本呈现“平原区生产功能主导、中心城区及乡镇中心村生活功能主导、山区乡镇生态生活功能主导”的分布特征,其中生产主导功能区和生态生活复合功能区居多,面积占比分别为27.27%和24.38%。建议生产主导功能区积极发展现代化农业及旅游业,促进乡村产业振兴;生活主导功能区适度推进农村公共服务设施建设,促进乡村生态宜居;生态主导功能区坚持生态优先,保障生态空间功能发展;兼具2种以上优势空间功能类型的复合功能区,应结合区域自身及周边乡村的空间特性,宜生产则生产、宜生活则生活、宜生态则生态,优化布局“三生”空间;而复合功能区中“三生”功能均处于劣势的乡村,则需要结合“三生”空间功能发展的迫切程度,合理展开村庄空间规划和重构。研究结果可为乡村振兴战略实施下的乡村发展规划编制和建设实践提供指导。

乡村大旅游的构建理想与旅游终极目的的回归——以光山县边地潜开发区马畈周区为例

目前乡村旅游开发中的最大弊端在于对旅游的终极目的认识不清,从而导致经济目的优先,乡村原始的文化和自然资源遭到严重破坏。我们应该从长远着眼,从边地潜开发区着手,构筑乡村大旅游的建设理想,实现旅游终极目的的回归。
