实施林业血防工程 确保国家生态安全

<正>现在,我国的林业形势非常好,特别是中央九号文件出台以后,林业战略工程受到党中央国务院的高度重视。过去,林业主要集中在用材林上,所以林科院的项目很多是围绕速生丰产林的。自从中央九号文件和战略出台以后,国家把林业放在很高的一个位置上,树立了林业三生态,即生态建设、生态安全和生态文明的战略思想,在这个三生态思想的指导下,林业已经不仅是搞用材林,而是放在国家安全的范围内。

Using Digital Earth to Expose Students to GIScience

Students in U.S. geography programs face particular challenges that may discourage them from taking advanced GIScience courses and considering geospatial careers. This article provides a preliminary discussion of the development, delivery, and evaluation of a University of Colorado Colorado Springs sophomore-level, required geography course designed to address this concern. The course, Digital Earth (DE), introduces students to the principles, concepts, and applications of major geographic information technologies (GITs) early in their academic careers. The success of DE is evaluated by examining the extent to which the course excited students about GIScience and motivated them to take higher level elective geospatial courses. Results suggest that DE generates considerable student interest in GIScience, prepares students reasonably well for elective courses, and greatly inspires them to seek a geospatial career.     

Converting Brazil's pastures to cropland: An alternative way to meet sugarcane demand and to spare forestlands

Brazil seeks to rapidly increase its agricultural production to meet future demands, especially for sugarcane, which is an agricultural commodity and a biofuel source. In this paper, we explore how to achieve this increase without compromising existing forestlands. We propose that it is possible to substantially expand sugarcane production in Brazil while avoiding further environmental losses and the indirect land use changes often associated with them, such as deforestation. This task could be accomplished by converting existing pasturelands with agricultural potential into cropland. A great deal of pastureland exists in Brazil. Thus, we addressed the following questions in this study: (1) where are the most suitable pasturelands for sugarcane located geographically and (2) what potential do these pasturelands have for sugarcane production regarding their physical suitability and other significant factors, such as infrastructure availability and socioeconomic factors. We conducted a land suitability analysis using a spatial location model based on multicriteria decision-making and geographic information systems (GIS) to identify the cultivated pasturelands most suitable for conversion to sugarcane production in Brazil. “What if” scenarios were built to determine how changes in the subjectively derived weights of the priority criteria would modify the spatial distribution of the suitability classes relative to the MCDA model and demonstrate the robustness of the crop suitability assessment. The most suitable pastureland areas for conversion to sugarcane production were predominantly located in Minas Gerais, São Paulo, Paraná, Goiás, Mato Grosso do Sul, Mato Grosso and Pará. These zones have large contiguous areas of pasture with moderate and high agricultural potentials for sugarcane production. The total estimated area of cultivated pasturelands with moderate or high suitability for sugarcane production was 50 million hectares, which is much larger than the area currently used for sugarcane production in Brazil.     

A path that buys time to decide where to go

This paper considers the problem of planning a path in a circumstance where its origin is given, but its destination is not specified and is to be selected from among a set of candidate destinations during a trip. A situation like this may be experienced by a group of people who have different preferred destinations, as well as by an individual who is simply indecisive about where to go. To resolve such an uncertainty, one may stay at the origin until he decides on a destination, or choose to proceed on some path that does not overly deviate from a shortest path, whichever destination is eventually chosen, and make a decision on the way. The latter action is sensible when the risk of traveling longer is outweighed by the benefit of buying more time for a better destination decision. The problem of finding such a time-buying path is formulated and a simple algorithm is developed for its solution. Some extensions and applications are also discussed.
