长期以来,耕地压力因与粮食安全联系密切而备受关注。云南省山区自然条件差,耕地总体质量不高。该文选择州(市)级为尺度,测算全省16个州(市)耕地压力指数并进行分级,揭示各州(市)耕地的紧张程度,为合理地确定全省及各州(市)耕地保有量等目标和制定耕地保护策略提供基础依据。研究表明:全省16个州(市)中,只有德宏州属“无压力”级;曲靖市和保山市属“警戒压力”级;玉溪市和昭通市耕地压力达“中压力”级;而昆明市和怒江州耕地压力达到了“高压力”级;其余9个州(市)的耕地压力等级均为“低压力”级。
For a long time, the pressure on cultivated land has attracted much attention due to its close relationship with food security. Yunnan mountainous natural conditions are poor, the overall quality of cultivated land is not high. In this paper, the state (city) level is selected as the yardstick, and the cultivated land pressure index of 16 provinces (cities) in the whole province is calculated and graded to reveal the tenseness of cultivated land in each state (city) Quantity and other goals and to develop a protective strategy for arable land to provide the basis for. The research shows that among the 16 states (cities) in the province, only Dehong prefecture belongs to “no pressure” level; Qujing and Baoshan City belong to the “warning pressure” level; and the pressure on cultivated land in Yuxi and Zhaotong reaches up to “ While the pressure on cultivated land in Kunming and Nujiang reached the ”high pressure“ level; the cultivated land pressure levels in the remaining nine states (cities) were all ”low pressure".
