The primary aim of Wood Structure and Environment is to reveal the hidden ecological richness in stems and roots from trees, shrubs and herbs. The detailed, lucid text will inspire researchers to consider the anatomic microcosm of wood plants and use it as a retrospective source of information, solving problems related to ecophysiology, competition, site conditions, population biology, earth science, wood quality and even human history.

This book contains the results and conclusions of extensive research on the causes and effects of acidification of forests/forest soils and heathland in the Netherlands. In 1985 the Dutch Priority Programme on Acidification was started in order to give a more concrete form to the increasing interest of policy-makers in the effects of air pollution on ecosystems in particular. In the last three years, the research has focused on obtaining a more accurate estimate of the emission of ammonia on the deposition of SOx, NOy and NHx, and also on quantifying effects on forest and heathland ecosystems. This quantification of effects included experimental work model analyses, and derivation of critical loads and levels for forest and heathland ecosystems. Furthermore, scenario analyses were made with the Dutch Acidification Systems Model (DAS) in order to evaluate the effectiveness of policy measures. The research itself, which formed the basis for this book, has been described in the reports on individual projects. A summary of the scientific results and conclusions is given in thematic reports (added as annex). An independent Review Team has provided a critical assessment of the research carried out since 1988. The Review Report has been incorporated as annex.

At a meeting of dendrochronologists an American colleague described the effects of volcanic eruptions on annual ring formation in bristlecone pines. I knew very little about either volcanoes or American pines! At the same meeting European scientists spoke on the dendrochronological dating of lakeshore settlements and the effects of larch bud moth attack on trees in the Alps. It is possible that American participants were not in a position to fully appreciate these papers either. In other words, dendrochronology is an extremely interdisciplinary science; its facets range from modern statistics on wood anatomy to the history of art. It is difficult even for dendrochronol ogists to keep in touch with the whole spectrum, and even more difficult for the layman to obtain an overall view of the many methods and fields of application. In recent times specialisation has begun to hinder communication be tween the various sectors. Archaeologists, for instance, set up their own dendrochronological laboratories and construct independent chronologies to serve their particular interests. The scientific institutions which previously carried out such work are now turning more and more to strongly statistically or biologically-oriented questions. The full wealth of information contained in tree rings, however, will be revealed only when dendrochronologists make a concerted effort to relate the findings of the different fields. In spite of inevitable specialisation, it is necessary that the expert concern himself with the work of his colleagues.

Air pollution poses a serious threat to human health and the environment worldwide. It contributes significantly to regional and global atmospheric issues such as global warming, acidification and depletion of the ozone layer. It affects every living thing, including all kinds of vegetation on which we depend for our survival. Although several works have appeared on air pollution, few, are able to provide the broad background that encompasses the whole gamut of plant responses to atmospheric insult. This multi-authored work integrates the varied plant growth responses to the pollution stress; the focus of the attention is plant rather than pollutant. This portrays a clearer picture of plant performance versus air pollution, and helps develop a better insight of the pollution-based disturbances at the different levels of plant life. The book shall interest both students and researchers of environmental botany and forestry as well as all those who love plants and have any interest towards global vegetation and environmental health.

Following a research design of "e;phenomenal description a' theoretical analysis a' model construction a' empirical test a' policy suggestion"e;, this book aims at proposing "e;National Resources and Environment"e; (NRE) -constrained urbanization theory and establishing a measurement system for appropriate level of urbanization, which will serve as theoretical and empirical bases for measurement of appropriate level of urbanization under NRE constraints. Based on systematic review of previous researches on NRE-constrained urbanization at home and abroad, this book first summarizes the mechanism and rules of NRE-constrained urbanization with reference to theories of Wooden Barrel, Climbing Hill, Migration, Economic Growth and Ecology. By using the theory of endogenous economic growth and the theory of constraints, it further deduces the model of "e;resource drag"e; in urbanization caused by shortage of resources and environment and that of "e;resource curse"e; in urbanization caused by resource endowment respectively. The appropriate NRE-constrained urbanization is deconstructed into four sub-objectives including the level, speed, structure and scale, and thus a measurement model is proposed. Based on the analysis structure of NRE-constrained urbanization, major NRE effects and key constraint factors of NRE on the urbanization of Jiangxi province are studied. Econometric analysis of panel data is also conducted to examine various effects on the process of urbanization. By using theories and models of NRE-constrained urbanization, this book examines the "e;resource drag"e; and "e;resource curse"e; in Jiangxi's urbanization; deduces the equilibrium level of NRE-constrained urbanization in Jiangxi by using the econometric model and compares the actual compatibility of the level and speed of urbanization in Jiangxi during 1978-2008 by using environmental capacity constrained Logistic model. It further examines the compatibility of scale and space distribution in Jiangxi's urbanization and calculates optimal city scale for Jiangxi by using the measurement model of the structure of NRE-constrained urbanization. At last, based on the aforementioned analysis, this book summarizes main findings and future prospects of the research, and provides policy suggestions on promoting the appropriate process of urbanization. The research aims at the mechanism and rules of urbanization progress under constraint of the NRE based on systematic summary of the effect and constraint of NRE on urbanization. A measurement model for the appropriate progress of urbanization is proposed based on the analysis of NRE-constrained urbanization theories. Meanwhile, the general conclusion will be applied to typical areas and tested by an empirical study, so as to test and develop relevant theories, and give a comprehensive evaluation on the coordination of urbanization with NRE. In this way, lessons can be learned and summarized for similar regions to advance urbanization and utilize NRE. More specifically, the objectives of this book involve: (1) to reveal the mechanism and rules of NRE-constrained urbanization theoretically; (2) to propose a measurement model and methods for monitoring the appropriate progress of urbanization under constraint of NRE; (3) to conduct an empirical study on Jiangxi Province, evaluate its proper NRE-constrained urbanization process from the aspects of level, speed, structure and scale during "e;11th Five Year Plan"e; by quantitative evaluation on Jiangxi's urbanization, NRE, and thus giving suggestions for policy making.
