The world grain production was increasing rapidly during 1950 to 1984,and the average increasing rate was 2. 9 percent per annum during this period; but the increasing rate, however, was remarkably reduced to 0. 7 percent per annum during 1984 to 1992. The author holds that the rapid increasing rate for the former period is caused by the progress and application of science and technology to agriculture.

The world grain production was increasing rapidly during 1950 to 1984,and the average increasing rate was 2. 9 percent per annum during this period; but the increasing rate, however, was remarkably reduced to 0. 7 percent per annum during 1984 to 1992. The author holds that the rapid increasing rate for the former period is caused by the progress and application of science and technology to agriculture. According to the statistics it is found that the increasing rate of grain production per capita was more than 30 percent per decade during 1950 to 1980,but the rate tended downwards to negative value after middle 80's. The author considers the main causes for slowing or drop- . ping of world grain production are the globle deterioration of agro-eco-environment and the rapid increasing of world population. Then the author discussed the possible ways for preventing the dropping of world grain production.

1950—1984年全世界粮食生产以较大的幅度增长,其间的平均增长率为每年2.9%;但1984—1992年粮食增长的幅度明显下降,平均为每年0.7%。以人均粮食来统计,1950—1980年期间,人均粮食每10年增长速率超过30%,至80年代中期人均报食开始减少。前期粮食增长较大的主要原因为科学技术的进步;而后期粮食增长减缓或衰退的主要原因被认为是全球(农业)生态环境的劣变和人口的不断增多。本文试图探讨防止人均粮食下降的主要途径。

The effects of the changes of Dongting Lake on agro eco environment of the Lake area have been discussed. It is concluded that the changes of the Lake has brought into a series of eco environmental problems such as the decline of the lake effect, the increase of the frequency of flood and water logging, the more serious of soil gleying, the prevalence of snail fever and the damage of aquatic resources. The strategy and the countermeasures for protecting and improving of the agro eco environment...

The effects of the changes of Dongting Lake on agro eco environment of the Lake area have been discussed. It is concluded that the changes of the Lake has brought into a series of eco environmental problems such as the decline of the lake effect, the increase of the frequency of flood and water logging, the more serious of soil gleying, the prevalence of snail fever and the damage of aquatic resources.

讨论了洞庭湖演变对湖区农业生态环境的影响,认为湖体演变带来了诸如湖泊效应降低、洪涝灾害频繁、土壤潜育化严重、血吸虫病流行以及水产资源破坏等一系列生态环境问题,并提出了保护和改善湖区农业生态环境的对策与措施。

According to the results of a wet dry rotation cropping experiment, the regularities of growth, decline and changes of crop insect (destructive and beneficial) weed communities were studied. The approaches of using those regularities for the development of production, maintenance of farmland ecosystem balance, optimization of agro eco environment and maximization of crop yield were also discussed.
