土地资源学是研究土地资源的形成与演变过程、分类与分布规律、数量与质量评价,以及土地资源开发、利用、保护与管理的一门综合性学科。近些年来,我国在土地调查、土地评价、土地整理、土地可持续利用、土地利用规划与资源战略、土地利用优化配置与集约利用、土地资源安全与生态友好型土地利用模式等专业领域取得了显著进展。论文着重分析土地资源学科研究的新进展,对近年来我国土地资源学科最新成果及其在国民经济与社会发展中的应用、成效和前景进行评析,对我国土地资源学科发展趋势进行展望,提出新时期土地资源学研究的主要方向和重点领域。

Land resources science is a new discipline taking land resources as an integrated research object. Marked progress made in comprehensive research covers the following aspects: investigation and exploitation of land resources;evaluation of land resources types and characteristics,quantity and quality;land resources consolidation and transformation;sustainable land resources use and management;land use general planning and land resources strategy;optimal land use allocation and its intensive use; and land resources security and ecological friendly land use model.Based on the analysis of the research progress in land resources sciences and reviewing the main achievements of Chinese land resources discipline in recent years, this paper discusses deeply on the tasks and prospects of land resources discipline development along with the rapid national economic and social development,predicts the developmental trend of land resources science on the basis of analyzing the developmental goal and prospect of land resources discipline.Furthermore, it puts forward that there are eight key development fields and main research directions of land resources science in China.The key research fields and directions of land resources science in the future are as follows:(1)To enhance the theoretic study of land resources discipline,especially land resource classification,driving forces and impacts of LUCC,innovation of land resources discipline system;(2)to attach importance to macro strategic study of land resource,especially the optimal strategy of land resource and sustainable use models under the guidance of sciences developmental views;(3)to promote the research and application of the new ideas,new principle,new technology and new methods of general land use planning in order to serve well for the regional decision-making of socio-economic harmonious development;(4)to study deeply the evaluation index system,technical methods of intensive land use,probe into the criterion of optimal land use and standard of regional and industrial land use;(5)to strengthen research of the principle,model and demonstration of land resource safe and ecological friendly land use in order to put forward the sciences guidance for realizing sustainable land use;(6)to study theory,method and ensuring system of the modern landscape land consolidation,and the mechanism and models to upgrade intergraded productivity of land resources;(7)to probe into the management model and policy of rural land resources,especially study the science ways for land-lost farmer employment,and food security and arable land protection based on the analysis of new condition and new question of regional development; and (8)to study and develop the land resource information system,and make the most of"3S"technology,model method and expert decision-making system to realize the informationization and systematization in the process of land resource research and management.
