Abstract

China's rapid urbanization and industrialization over the past four decades have profoundly transformed patterns of rural land use. Effectively optimizing rural land resources remains a critical challenge for the government. To address this challenge, China launched the whole-region land consolidation (WCLC) initiative in 2019; but systematic and quantitative evaluations of its outcomes have been scarce. Here, we establish a framework to evaluate production–living–ecological spaces (PLES) by calculating the PLES index (PLESI) based on high-resolution remote sensing data covering Chinese townships from 2010 to 2023. We assess the effects of WCLC through spatial analysis techniques and the Difference-in-Differences (DID) model. The results confirm that WCLC has significantly optimized PLES in rural China, leading to a 3.65 % increase in the PLESI of pilot towns. The production space index (PI) and living space index (LI) rose by 3.83 % and 7.51 %, respectively. However, the effects of WCLC on rural PLES vary significantly across regions: eastern areas show enhanced production and living functions, while less developed regions exhibit improvements in production and ecological functions. In the short term, WCLC may accelerate the fragmentation of ecological landscapes. Over 80 % of respondents believe WCLC has been effective and are satisfied with the outcomes. Our findings offer valuable insights for China and other developing countries in comprehensively advancing urban-rural land planning to optimize their territorial spaces.

全区域土地综合整理对中国农村生产-生活-生态空间优化的影响评价

过去四十年来，中国快速的城市化和工业化深刻地改变了农村土地利用模式。有效优化农村土地资源仍然是摆在政府面前的严峻挑战。为了应对这一挑战，中国于2019年启动了全区域土地整理（WCLC）计划；但对其结果的系统和定量评估一直很少。本文基于2010 - 2023年中国城镇高分辨率遥感数据，通过计算生产-生活-生态空间指数（PLESI），构建了生产-生活-生态空间评价框架。我们通过空间分析技术和差异中的差异（DID）模型来评估WCLC的影响。结果表明，WCLC显著优化了中国农村PLESI，试点乡镇PLESI提高了3.65%。生产空间指数（PI）和生活空间指数（LI）分别上升3.83%和7.51%。然而，不同地区的农村生态环境差异显著，东部地区的生产和生活功能增强，欠发达地区的生产和生态功能则有所改善。从短期来看，西部西部地区可能会加速生态景观的破碎化。超过80%的受访者认为WCLC是有效的，并对结果感到满意。研究结果为中国和其他发展中国家全面推进城乡土地规划，优化国土空间提供了有价值的参考。

期刊介绍： Habitat International is dedicated to the study of urban and rural human settlements: their planning, design, production and management. Its main focus is on urbanisation in its broadest sense in the developing world. However, increasingly the interrelationships and linkages between cities and towns in the developing and developed worlds are becoming apparent and solutions to the problems that result are urgently required. The economic, social, technological and political systems of the world are intertwined and changes in one region almost always affect other regions.
