In addition, adhering to the prin- ciple of partition prevention and treatment, some guiding prevention and control measures of the natural zone passed by the project and soil erosion control district were determined, which provided scientific references and technical support for the rational layout of water and soil conservation and ecological restoration measures in Dina 2 gas field.展开更多

The reconstruction of streets is the first issue being looked at. In the past few years,experiences have beengained and problems encountered. For instance, only some sections of the streets are reconstructed, the scale and de-velopment program of reconstruction are decided without any comprehensive, conceptual planning program, Thispaper attempts to analyse the reasons and defects of the past practice and some suggestions are made on improve-ment measures. It is pointed out in particular, that the transformation of streets should be based in the need, devel-opment potential, characteristics and specific role of the cities in order to enable the streets to be reconstructed incoordination with the transformation of the cities as a whole.展开更多

Affected by both natural and human factors, a complex interdependency is found among the regional changes in construction area, GDP and population. A quantitative analysis of the four phases of the regional land use data extracted from remote sensing images and socioeconomic statistics spanning 1979 to 2009 demonstrates that the proportion of construction area in the PRD increased from 0.5% in 1979 to 10.8% in 2009, accompanied with a rapid loss of agricultural land. An increase of one million residents was associated with an increase of GDP of ap- proximately 32 billion yuan before 2000 and approximately 162 billion yuan after 2000. Be- cause the expansion of construction area has approached the limits of land resource in some cities of the PRD, a power function is found more suitable than a linear one in describing the relationship between GDP and construction area. Consequently, the Logistic model is shown to provide more accurate predictions of population growth than the Malthus model, particu- larly in some cities where a very large proportion of land resource has been urbanized, such as Shenzhen and Dongguan.展开更多
