Dispersed consumer amenities such as shopping and cultural attractions greatly influence land use patterns and rent gradients. Lai and Tsai generalize the traditional Alonso–Mills–Muth model by introducing a monopoly vendor and show that the vendor
will choose a boundary location. We generalize their model by allowing for inter-city shopping, which is very common in the real world. The location choice of a monopoly vendor and the consequent changes of urban configuration in two adjacent cities
are discussed. This paper shows that as the distance between two CBDs decreases, the vendor may choose to locate at an inner city boundary, at the mid-point between the two cities, and at one of the outer boundaries, respectively. In many cases, a core-periphery
This paper investigates the feasibility of using Landsat TM data to retrieve leaf area index (LAI). To get a LAI retrieval model based ground reflectance and vegetation index, detailed field data were collected in the study area of eastern China
, dominated by bamboo, tea plant and greengage. The AA. discuss the sensitivity of parameters in the LAI retrieval model, and retrieve a suitable LAI model for the sub-tropical vegetation based on Landsat TM data, and validate the model with ground-based LAI
Spatial and temporal variation of global LAI during 1981-2006
In this paper, the AA. use a long-term leaf area index data (LAI) to identify where changes happened and where has experienced the strongest change around the globe during 1981–2006. Results show that, over the past 26 years, LAI has generally
increased at a rate of 0.0013 per year around the globe. LAI has prominently increased in Europe, Siberia, Indian Peninsula, America and south Canada, South region of Sahara, southwest corner of Australia and Kgalagadi Basin; while noticeably decreased
in Southeast Asia, southeastern China, central Africa, central and southern South America and arctic areas in North America. The geographic distribution of global LAI trend over the 26 years is mapped, and the hot-spot areas with extreme trends are identified.
Human geographies of climate change : landscape, temporality, and lay knowledges
The AA. bring together work on landscape, temporality and lay knowledges to propose new ways of understanding climate change. A focus on the familiar landscapes of everyday life offers an opportunity to examine how climate change could be researched
Forderung des Umweltbewusstseins durch die Gestaltung eines Freizeit-und Erholungsparkes in einer sozialistischen Stadt. (Promoting environment-mindedness by laying out a recreation park in a socialist city)
Optimum organization of the environment is a extremly complex group of tasks to be dealt with by architects and town planners. It was necessary to take into account the opinions and ideas of the resident in the process of laying out an adequate
Leaf area index (LAI) of natural vegetation is recognized as the most important variable for measuring vegetation structure over large areas, and for relating it to energy and mass exchange. In this paper, according to the statistical analysis based
on a lot of forest plots, the mathematical models of LAI distribution patterns in the hydro-thermal spaces for 5 coniferous forest types in China were established.
Using a case study of recreational angling, the A. shows how fish in English rivers and lakes are counted and anglers act as lay or amateur knowledge-producers in the state's metrological knowledge-practices. She shows how, to support environmental
measurement, the state manages not only the environment and fish, but also anglers as lay knowledge-producers, using both regulation and economic incentives.
The method for simulating the temporal and spatial distribution patterns of leaf area index (LAI) and biomass at landscape scale using remote sensing images and surface data is discussed in this paper. The method is based on Landsat Thematic Mapper
(TM) images (May 23, 1985; September 2, 1999) and LAI and biomass measurements at patch scale. The study area is Changbai Mountain Nature Reserve in southeastern Jilin province.
Der Tayrona-Trockenwald Nord-Kolumbiens. Eine Okosystemstudie unter besonderer Berücksichtigung von Biomasse und Blattflächenindex (LAI). (La forêt tropicale sèche de Tayrona en Colombie du Nord. Une étude d'écosystème compte tenu en particulier de
The drought deciduous lowland forest of the Caribbean coast near Santa Marta (Columbia) has been investigated for biomass, leaf area index (LAI), and foliage dynamics at three different stands. The physiognomical differences depending
on the different ecological factors are reflected within all measured paramenters. Living wood biomass as well as the mean actual LAI could be taken into account as best indicators of stand quality.
Sasaki generalizes the urban-growth control model developed by Bruekner and Lai, and concludes that the optimal urban-growth control is less (more) stringent than the B-L model when an agglomeration effect (public-good-provision effect
The major objective of this research was to quantify the outflow of meltwater and precipitation-generated runoff from the region that lay on and adjacent to the southern margin of the Laurentide Ice Sheet, during a major period of glacial melting
