The aim of research was to assess the changes of annual radial increment of Scots pine forests in the vicinity of intensive and moderate industrial pollution of “Achema” factory producing mineral fertilizers. Our results indicate that the radial growth of the pine tree can be divided into three different periods: growth promotion, growth inhibition and growth recovery. Low levels of nitrogen emissions were beneficial for tree growth: the radial increment in the intensive and moderate pollution zones increased by 15–25% and 10%, respectively compared to control. During the growth inhibition period, the total annual industrial emission was 37–40 kt, and 40–45% radial growth loss was observed for the closest and 15–20% for the most distant stands. The radial growth decrease slowed down and the recovery of damaged stands began in 1990–1992 then air pollution was considerably reduced. The rate of forest recovery was high for the most damaged stands: their radial growth was close to control in 2000–2011. 相似文献

An overview of environmental distribution of tritium in the Danube basin in Yugoslavia during the period 1976-1990 is presented. Temporal and regional variations of environmental tritium in the Danube along its flow (1425-847 km from the confluence) and its tributaries (the Sava, the Tisa, the Velika Morava and the Timok) at various locations, as well as in alluvial groundwaters, are given. In Belgrade, monthly values of tritium in rainfall ranged from 1.1 to 18.3 Bq litre(-1), with a maximum in the late spring and early summer months. The half-life for decline in concentration was estimated as 8.3+/-1.0 years. The total amount of tritium deposited in the first 6 months during 1976-90 was 35% larger than in the second 6 months for the same period. Seasonal variations were noticeable in rivers and groundwaters, but these were greatly attenuated and smoothed for the latter. Tritium content in the monthly composite samples from the river in the Belgrade region varied between 2.5 and 18.2 Bq litre(-1) for the Danube and from 1.5 to 16.8 Bq litre(-1) for the Sava. The yearly mean values along the Danube and its tributaries ranged from 2.4 to 15.9 Bq litre(-1) with individual measurements 1.0-30.2 Bq litre(-1). The half-lives were between 6.9+/-1.7 for the Velika Morava and 9.4+/-0.9 for the Danube. Groundwaters, particularly ones in the Ranney wells, followed changes of tritium content in the rivers with a time lag from a few days to a month. During the period of observation, tritium content decreased in alluvial waters with half-lives from 9.9+/-1.6 (Belgrade area) to 7.3+/-1.8 (the Velika Morava). 相似文献

The varied and very dynamic landscape with a high biological diversity is a distinctive feature of the Curonian spit at the
regional scale. Throughout the 20th century the main morphodynamic trend in the littoral of the Curonian spit was shoreline
grading on the lagoon side, whereas on the marine side the increasing erosion at the foot of the spit, and increasing accretion
at the head of the spit prevailed. The results of a discriminant analysis (Wilkes’ λ = 0.001626 and F = 29.267 when p < 0.001) show that sites with prevailing erosion, accretion and sediment input from the drifting dunes form regular inter-related
spatial structures in the littoral with distinctive resulting discontinuities of the sediment drift along the lagoon coast.
Dune littoral cells are characterized by Aeolian sediment input and distribution ‘down-drift’, (usually northwards) from the
source. The most likely changes in the current development trends of the lagoon shore zone of the Curonian spit are related
to expected climate changes and further slowing down of the dune drift. The probability of storms and ice-drift events, and
their impact on coasts is expected to increase as a result of climate change. The dune advance will gradually slow down, and
with it, the sand input to the coastal zone will decline. In this paper, we define integrated shoreline management as a system
of long-term shoreline management measures, which is based on a littoral cell approach and aimed at harmonizing human activity
in the coastal zone with the natural development of the shoreline. We propose an integrated management program for the lagoon
shoreline of the Curonian spit, which is site-specific for each littoral cell as a coastal management unit. Drifting dunes
and seaside beaches are the natural amenities, which are best known and best appreciated on the Curonian spit by 49% of the
respondents representing the total Lithuanian population. A responsible tourism development should be considered as the key
means for proper appreciation of the drifting dunes and natural coasts by society, which means to acknowledge and cherish
the aesthetic and conservation values of dune and coastal landscapes of the Curonian spit as a World Heritage Site. There
are at least two pre-conditions for this: (1) to provide visitors with sufficient information about diverse values and functions
of the Curonian dunes and coasts within a broader regional and global heritage conservation context; (2) to enable tourists
to enjoy the most impressive dune and coastal landscapes at close range. In this paper we propose to encourage active dune
tourism, to reintroduce grazing into the Curonian dune areas, to restore and to preserve the most impressive landscapes of
the highest white drifting dunes by bringing the blown out sand from the leeward foot of the dunes back to the crest artificially. 相似文献
