云南九大高原湖泊流域现行管理体制及其完善建议

云南省湖泊面积达到30 km2以上有9个,分别为滇池、阳宗海、抚仙湖、星云湖、杞麓湖、洱海、泸沽湖、程海和异龙湖,具有独特的自然地理条件和生态服务功能,在全省经济发展和生态文明建设中占有举足轻重的地位。近年来对9大高原湖泊的治理已取得一定成效,但水质日趋恶化仍是当前面临的突出问题,主要原因是现行的湖泊流域管理体制机制不够完善,未能适应流域经济的快速发展以及流域保护治理的需求。分析和总结了云南9个高原湖泊流域管理体制的现状及存在的问题,在国内外湖泊流域管理案例和成功经验的基础上,根据9大高原湖泊流域自身特点,提出了完善管理体制的建议。

A hundred and more years of plant protection in the Netherlands

At the occasion of the Centenary of the Netherlands Society of Plant Pathology a reflection on past, present and future of plant protection, the subject matter of the Society, was thought to be appropriate.Developments in plant protection are projected against a general stream of thought. Three turning points are distinguished which can be seen as paradigm changes. The first occurred around 1890, when the concept of pathogenitism gained its final victory over autogenitism. The second occurred around 1940, when the public outlook on human and plant health changed drastically due to the advent of chemotherapeutants. The third occurred around 1990 when a clear change in public thinking on agriculture, environment and plant protection became apparent. The background of these changes is sketched in a personal manner.Some ideas on plant protection beyond the year 2000 are given, based upon recent developments in the Netherlands to which the Society contributed in its own way.     

An advisory model for control of Puccinia recondita in winter wheat

Epidemics ofPuccinia recondita and resulting yield loss of winter wheat were studied in field experiments over three seasons in the Netherlands. Results are reported and used to construct an advisory model for control of brown rust, based on rust monitoring. If the fraction of leaves with rust (I) at a certain development stage is determined, the average number of rust sori per leaf (M) was estimated by: M=EXP(1.84+1.39ln(ln[1/(1-I)]). The final number of sori per leaf (Mf) at early dough was forecast by an exponential growth: Mf=M·EXP(RGR·t). The relative growth rate (RGR) averaged 0.163/day and the forecasting period, t, until early dough, was derived from published data. The forecast number of sori-days per leaf (S, AUDPC-value) was then obtained by: S=(Mf-M)/RGR. Yield loss (kg/ha) by brown rust was 1.15 times the number of sori-days per leaf at low rust intensities. The efficacy of the fungicides used was 85%. The forecast avoidable yield loss (L, kg/ha) was calculated by: L=0.85 (1.15 S). Economic thresholds for brown rust control at different development stages are given for Dutch wheat fields at a cost level of 270 kg/ha for one fungicide application.
