Suitability assessment of arable land reserve and its spatial differentiation in Heilongjiang Province
摘要
Abstract
The development of arable land reserves is an important way to alleviate the land overtaken problem by construction. In order to find out the distribution characteristics of arable land reserves in Heilongjiang Province, this paper applied the multi-source data to construct a suitability assessment index system from the perspective of ecological conditions, site conditions, climate conditions, and locations, to evaluate the suitability of arable land reserves in Heilongjiang Province. Results show that the amount of arable land reserves in Heilongjiang Province is 110.55×104 hectares, and arable land reserves are dominated by other grasslands, marshes, beaches, and saline land, and mainly concentrated in Daqing, Heihe, Suihua and Jiamusi. Arable land reserves showed signiifcant spatial clustering characteristics. Daqing and its surrounding counties or districts showed the high-high type of aggregation and urban or suburban areas show the low-low type of aggregation. While the low-high type of aggregation is more fragmented and there is no high-low type of aggregation in Heilongjiang Province. Aggregation characteristics of arable land reserves showed obvious homogeneity. In the future, the Government should focus on Daqing City and its surrounding areas to develop arable land reserves in Heilongjiang Province.关键词
