资源相对匮乏和粗放利用问题在我国很多地区较为突出。以湖南省为例,一方面,战略性资源日益匮乏,自给能力不断下降。目前全省人均耕地0.86亩,为全国平均水平的61%,有9个市、州56个县(市、区)人均耕地低于联合国确定的0.8亩警戒线,且耕地后备资源不足。水资源总量相对较丰沛但季节性缺水、工程性缺水、区域性缺水、水质性缺水现象比较严重。尤其是对经济发展起主要 The relative lack of resources and extensive use of the problem in many parts of our country more prominent. Take Hunan as an example. On the one hand, strategic resources are increasingly scarce and their self-sufficiency is declining. At present, per capita arable land in the whole province is 0.86 mu, which is 61% of the national average. Per capita arable land in 9 cities and 56 prefectures (cities and districts) is lower than the warning line set by the United Nations of 0.8mu, and there is not enough cultivated land reserve resources. Relatively abundant water resources but seasonal water shortages, engineering water shortages, regional water shortages, water quality is more serious water shortages.
