摘　　要：土地是承载粮食生产、经济发展和生态环境建设的基石,面对生产技术进步和人类对土地的大强度开发,有限的土地正承受着前所未有的压力。科学地测度土地的压力状态,是合理制定区域土地可持续利用管理的重要依据。从粮食生产、经济发展和生态环境安全三方面,探讨了黑龙江省土地的压力状态测度方法及其压力状态的空间分布格局与成因机理。结果表明：黑龙江省土地压力的各项指标具有明显的空间梯度分异规律,土地综合压力指数自西向东逐渐由高到低分布,耕地压力指数由北向南从低到高,建设用地沿西北—东南轴线方向逐渐减小,并在这一轴线的两翼向西南和东北方向逐渐降低,生态用地压力呈面状和团粒状分布格局。Land is the foundation of the construction, the food production, the economic development and the ecological environment. With the development of economy, land is under unprecedented pressure. Scientifically measuring the pressure state of the land is basis for the sustainable use of land. In this paper, food production, eco- nomic development and ecological environment security are considered. From those three aspects, the paper discus- ses the measure method of land pressure state and its spatial distribution pattern and genetic mechanism. Compre- hensive land pressure is increasing from west to east, the cultivated land pressure gradually increases from north to south, developed land pressure has decreased from northwest to southeast along a central axis of this area and has increased from northeast to southwest on both sides of the central axis, ecological land pressure has three highest pressure cores, i.e., Qiqihar, Daqing and Qitaihe.
