【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。
[Abstract]:Land is the cornerstone of carrying grain production, economic development and ecological environment construction. In the face of the progress of production technology and the intensive exploitation of land by human beings, limited land is under unprecedented pressure. Scientific measurement of land pressure is an important basis for rational formulation of regional sustainable land use management. From three aspects of grain production, economic development and ecological environment security, the paper discusses the measurement method of land pressure state in Heilongjiang Province, and the spatial distribution pattern and formation mechanism of the pressure state. The results show that the land pressure index of Heilongjiang Province has obvious law of spatial gradient differentiation, the comprehensive land pressure index gradually distributes from west to east to low, and cultivated land pressure index from north to south from low to high. The construction land gradually decreases along the north-west-southeast axis direction, and decreases gradually in the direction of southwest and northeast of the two wings of the axis. The pressure of ecological land is distributed in the shape of surface and pellet.
