Research on the Landscape Pattern Characteristics and Consolidation Zoning of Non-grain Cultivated Land in Economically Developed Areas—A Case Study of Yinzhou District,Ningbo City
The purposes of this study are to analyze the landscape pattern characteristics of non-grain cultivated land in economically developed areas,and to scientifically define the priority and zoning of non-grain cultivated land consolidation,to provide the references for the spatial governance of non-grain cultivated land.The research methods include morphological spatial pattern analysis(MSPA),comprehensive evaluation model and four quadrant method.The research results show that:1)the non-grain rate of cultivated land in Yinzhou District was 37.6%,and the non-grain rate within permanent basic farmland was 40.4%,the main types of non-grain cultivated land were economic crop planting,followed by seedling planting and aquaculture,and their spatial distribution showed a decreasing pattern from the southeast suburbs to the northwest urban area.2)The non-grain cultivated land in Yinzhou District was mainly composed of core and peripheral cultivated land types,and the non-grain utilization of core and peripheral cultivated land was occupied by aquaculture and economic crops,respectively.There were fewer perforated and circular cultivated land types.3)The evaluation of consolidation suitability and urgency can clarify the priority order of non-grain cultivated land consolidation,the proportion of priority consolidation areas,key consolidation areas,reserve consolidation areas.The general consolidation areas designated for non-grain cultivated land in Yinzhou District were 40.1%,15.1%,24.5%and 20.3%,respectively.The combination of different types of zones and the arrangement of consolidation timing can provide a basis for differentiated non-grain cultivated land governance strategies.In conclusion,it's necessary to pay attention to the landscape pattern characteristics of non-grain cultivated land.According to the combination differences of cultivated land conditions,utilization status and control policies,zoning and consolidation strategies for non-grain cultivated land can be scientifically formulated to improve the governance efficiency.
