摘　　要：在干旱半干旱地区,基于水资源约束的影响,科学绿化的关键要素在于“以水定绿”。但在绿化实践过程中,“以水定绿”的时空作用范围及植被-水文系统中的生态学内涵尚不明晰。为此,我们通过“以水定绿”的时空尺度特征入手,就水分限制下自然植被和人类活动的权衡对策、物种-种群-群落构建以及生态系统-景观范畴的生态水文过程等与干旱半干旱区进行人工建植的多种关键生态机制进行了分析探讨。在此基础上,针对“以水定绿”理念下的科学绿化提出了相关建议。In arid and semi-arid regions,based on the impact of water resource constraints,the key element of scientific greening lies in"greening based on water".However,in the process of greening practice,the spatial and temporal scope of the"greening based on water"effect and the ecological explanation in the vegetation-hydrological system are still unclear.Therefore,we analyzed and explored various key ecological mechanisms for artificial cultivation in arid and semi-arid regions,such as balancing strategies between natural communities and human activities under water constraints,species-population-community construction,and eco-hydrological processes in the ecosystem-landscape category,based on the spatiotemporal scale characteristics of"greening based on water".On this basis,relevant suggestions were put forward for scientific greening under the concept of"greening based on water".
