    摘要:

    为了科学评价区域资源与环境压力状况,为生态文明建设提供参考依据,构建了基于足迹家族的资源环境压力评价体系,并应用于云南省的资源环境压力评估。结果表明,1990-2013年,云南省生态压力由中上(Ⅱb)升至较高等级(Ⅲa);虽然林业碳汇23年来提高了73.28%,目前可中和全省14.67%的温室气体(GHG)排放,但碳足迹却增高了325.98%,致使GHG排放由较低(Ⅰb)上升至中下等级(Ⅱa);人均水足迹增速很小,可用水资源量较高,水资源压力虽很低(Ⅰa),但人均可用水资源量却以年均3.66%的速率减少;1990年以来,云南省的资源环境压力升高了一个亚级,由较低(Ⅰb)上升至中下等级(Ⅱa)。空间上生态压力变化较大,昆明、曲靖、昭通、文山、玉溪和红河等6市很高(Ⅲb),保山市和楚雄州较高(Ⅲa),大理州和临沧市为中上等级(Ⅱb),丽江、德宏、西双版纳、普洱等市(州)为中下等级(Ⅱa),怒江州和迪庆州分别属较低(Ⅰb)和很低等级(Ⅰa);GHG排放的空间差异较大,曲靖和昆明市为很高等级(Ⅲb),玉溪市较高(Ⅲa),红河市为中上(Ⅱb),西双版纳、怒江和迪庆3州属碳汇(Ⅰs),丽江和普洱市的GHG排放水平则低于全球应对气候变化目标的限定值,属很低等级(Ⅰa),其余地区较低(Ⅰb);空间上水资源压力亦不尽相同,昆明市的水资源压力很高(Ⅲb),楚雄州为中上等级(Ⅱb),玉溪市、大理州和曲靖市为中下等级(Ⅱa),其余地区很低(Ⅰa);资源环境压力的空间差异很大,昆明市很高(Ⅲb),曲靖市和玉溪市较高(Ⅲa),红河市中上(Ⅱb),昭通、文山、楚雄和大理州等市(州)中下(Ⅱa),保山市、临沧市和德宏州较低(Ⅰb),其余地区很低(Ⅰa)。在今后的发展中,云南省应严格保护耕地资源,推广农业高新技术,提高土地生产率;调整能源消费结构,大力发展清洁能源,减少GHG排放;加强森林保育,继续提高林业碳汇能力。使山清水秀的云南成为中国生态文明建设的一面旗帜。

    Abstract:

    In order to evaluate the regional resource-environmental pressure and to provide a reference for the construction of an ecological civilization, the author proposed an evaluation system considering the Footprint Family (Ecological, Carbon and Water Footprints). This system allowed for the study of resource-environmental pressure in Yunnan Province, China. The results revealed that, in Yunnan Province, the ecological pressure level increased from an above-average grade (Ⅱb) to a high grade (Ⅲa) in the period between 1990 and 2013. Forest carbon sequestration increased 73.28% in the past 23 years, which neutralized 14.67% of greenhouse gas (GHG) emissions in 2013. The Carbon Footprint increased 325.98%, which led to an increase in the level of GHG emissions from a low grade (Ⅰb) to a below-average grade (Ⅱa). The Water Footprint per capita grew slightly, and the available water resources were relatively high. As a result, the water resource pressure was very low (Ⅰa). However, the available water resources per capita decreased at an annual average rate of 3.66%. Since 1990, resource-environmental pressure in Yunnan Province increased a sub-grade, from a very low grade (Ⅰa) to a low grade (Ⅰc). Ecological pressure of individual cities varied throughout the province. Kunming, Qujing, Zhaotong, Wenshan, Yuxi, and Honghe each had a very high grade (Ⅲb). Baoshan and Chuxiong each had a high grade (Ⅲa), while both Dali and Lincang had an above-average grade (Ⅱb). Lijiang, Dehong, Xishuangbanna, and Pu'er each had a below-average grade (Ⅱa). Nujiang had a low grade (Ⅰb), and Diqing had a very low grade (Ⅰa). GHG emissions varied spatially as well. Qujing and Kunming both had very high grades (Ⅲb) and Yuxi had a high grade (Ⅲa). Honghe had an above-average grade (Ⅱb) while Xishuangbanna, Nujiang, and Diqing each had a carbon sequestration grade (Ⅰs). Finally, Lijiang and Pu'er each had a very low grade (Ⅰa), of which was lower than the target set for the control of global climate warming. The rest regions had a low grade (Ⅰb). Additionally, water resource pressure varied amongst the cities. Kunming had a very high grade (Ⅲb), while Chuxiong had an above-average grade (Ⅱb). Yuxi, Dali, and Qujing each had below-average grades (Ⅱa), and various other regions had very low grades (Ⅰa). The resource-environmental pressure too, was very different amongst the cities of the Yunnan Province. Kunming had a very high grade (Ⅲb) while Qujing and Yuxi both had high grades (Ⅲa). Honghe had an above-average grade (Ⅱb), and Zhaotong, Wenshan, Chuxiong, and Dali each had below-average grades (Ⅱa). Finally, Baoshan, Lincang, and Dehong all had low grades (Ⅰb), and various other regions had very low grades (Ⅰa). In the future, Yunnan Province should firmly protect cultivated land resources, promote agricultural high-new technology, and improve the productivity of land. Additionally, the province should adjust energy consumption structure, develop clean energy, reduce GHG emissions, strengthen forest conservation, and enhance carbon sequestration capacity. These measures would allow for the beautiful Yunnan Province to become a banner for ecological civilization construction in China.
