Forest ecosystems near conurbations. Final report; Ballungsraumnahe Waldoekosysteme. Abschlussbericht

Abstract

In Berlin forests the pollution impact on the ecosystem was investigated from 1986 to 1989. Data about soil characteristic, botany, vegetation, zoology, microbiology, climatology and air pollution were collected and analyzed comprehensivly. Vegetation shows characteristic damages caused by SO{sub 2} and possibly by O{sub 3}. Composition of vegetation and soil fauna is typical for acidic forests and shows no conspicous behaviour. The acid deposition is less than expected, but the high deposition of dust leads to concernable accumulation of heavy metals in the humus layer and to the deposition of nutrients, which results in good growth of the Pine; only with heavy damages in the crown, stem growth is lowering. The fine roots are growing mainly near the surface in the humic soil horizons. Their distribution, their mycorrhiza and their fine structure show no clear damages. Liming did not remove needle damages und didn`t improve the rooting system, but it changed population density of soil fauna and microorganisms, which are important for humus formation. For that reason liming can not be advised on comparable sites. (orig.) With 119 refs., 37 tabs., 77 figs.

[Deutsch] In den Berliner Forsten wurden in den Jahren 1986-1989 Untersuchungen durchgefuehrt, um die atmogenen und pedogenen Schadstoffbelastungen zu erfassen. Es wurden bodenkundliche, botanische, vegetationskundliche, zoologische, mikrobiologische, klimatologische und lufthygienische Daten erhoben und zusammenfassend ausgewertet. Die Vegetation zeigt deutliche Schaeden durch SO{sub 2} und evtl. auch durch O{sub 3}. Ihre Zusammensetzung und die der Bodenfauna ist charakteristisch fuer bodensaure Nadelwaelder und weist keine Auffaelligkeiten auf. Der Saeureeintrag ist unerwartet gering, jedoch fuehrt die Staubbelastung zu bedenklichen Schwermetallanreicherungen in der Humusschicht, aber auch zu Naehrstoffeintraegen, die zu gutem Wachstum der Kiefer fuehren; erst bei starker Schaedigung der Baumkrone verringert sich der Holzzuwachs. Die Feinwurzeln liegen ueberwiegend nahe der Oberflaeche in den stark humushaltigen Bodenhorizonten. Ihre Verteilung, ihr Besatz mit Mykorrhiza und ihre mikroskopische Feinstruktur liessen keine eindeutige Schaedigung erkennen. Kalkung behob nicht die Nadelschaeden und ergab keine Verbesserung im Wurzelbereich, fuehrte aber zu Veraenderungen in der Besiedelungsdichte mit Bodentieren und bei den fuer die Humusbildung wichtigen Mikroorganismen, weshalb eine Kalkung auf vergleichbaren Standorten nicht empfohlen werden kann.
