关键词	澜沧江人口耕地成人受教育年限交通植被可持续发展
摘要	澜沧江流域云南段以生物和文化多样性著称，但其生态环境承受着人口和经济活动的巨大压力。为了揭示上述压力的作用方式，作者在1996年10月-97年6月实地考察了其中上游沿江34个自然村，并收集了人口、耕地和成人受教育年限等数据。这些村落被分为“江边组”、“高山组”和“中游组”。前者交通条件较好，人口密度较高，但植被状况较差。数据处理结果表明：1）96年的人口和耕地面积呈显著正相关，而1981-96年的人口增量与人均耕地增量呈显著负相关，但在上游人口增量和耕地增量均呈显著正相关；2）96年的人口和耕地面积均显著大于81年的数值，但在下游96年人均耕地面积也有同样差别；3）“中游组”1981-96年耕地增长率显著高于“高山组”及“江边组”，而人均耕地增长率仅显著高于“江边组”，4）“中游组”和“江边组”村落的96年成人平均受教育年限显著大于“高山组”；5）三组村落人口增长率的差异不明显。上述结果暗示该区域的农业生产方式改进缓慢，而极低水平的受教育程度及其差异并不影响人的经济活动，人口密集地方的植被因人类活动多而使其比人口疏散的地方差。总之，澜沧江中上游地区通向可持续发展的路仍然很长。
其他摘要	The Lancang River Basin is well-known for their richness in biological and cultural diversities in Yunnan. But it faces human disturbances. To clarify the relations between human activities and environment, an on-the-spot survey of 34 villages in both banks of the middle and upper reaches of the basin in Yunnan was made to collect data on population, cultivated land, educated years of adults, vegetation cover, transpotation in 1996-97. Of the village ten were in the middle (M), twelve pairs at the upper part - one (L) and another welve at higher elevation (H). The villages of group L had more convenient communications than those of M and H. But the vegetation around the villages in group L was worse. The population density was higher in group L than that in H and M. Data analysis showed: a) The population significantly positively correlated with the cultivated land area in 1996. So did the increment of the population with that of the average cultivated land area in the upper. The increment of the population, however, significantly negatively correlated with that of the average cultivated land area. b) The population and the cultivated land area in 1981 were significantly more than those in 1996. So was the average cultivated land in 1981 in the middle. c) The growth rates of the cultivated land area in group M was significantly higher than that in L and H, yet the growth rates of the average cultivated land area in M was significantly higher only than that in L. d) Educated years per adult in groups M and L were significantly higher than that in H. e) The differences of the population growth rate among the three groups were not significant. The above results suggest that the styles of agricultural products have been improved slowly; social and economic activities of the villagers was not influenced by their law level education; the densely populated villages have worsened the vegetation than those with fewer villagers. In short, there is still a long way to realize the sustainable development in the Lancang River Basin.
