近年来中国耕地保护面临的突出困境在哪里?国土“三调”数据显示,2009年至2019年的10年间,全国耕地地类面积减少1.13亿亩,主要诱因并非非农建设占用,而是农业结构调整与国土绿化带来的农用地“内部流转”。从过去10年的地类转换看,既有耕地流向林地、园地等地类的情况,也有林地、园地等流向耕地的情况,总的来看,耕地净流向林地1.12亿亩,净流向园地0.63亿亩。
Imagine a vast shopping mall parking lot with thousands of individual parking spots and internal lanes (representing road segments within a cluster). No matter how complex it is inside, there are usually only a few key exits to the main roads. Our goal was to identify these natural "exits" for each map cluster. For instance, the complex road network around Amsterdam Airport Schiphol (see on OpenStreetMap) has many internal roads but limited primary access points.
