A STUDY ON LAND SYSTEM INNOVATIONS IN THE CONSTRUCTION OF SMALL TOWNS IN CHINA

The economic development in China and the rising of the living standard need to speed up the urbanisation. The development of small towns is an important way to Chinese urbanisation. Land use plays a very important role in the development of small towns. However there are many problems in the development of small towns, esp. in land use. The paper first discusses the land problems in the development of small towns. Such as much cultivated land lies idle, under utilization and waste of land, increasing illegal use of land, unstable contractual relationship for land use. The relationship between the development of small towns and land use is also studied. Then the guidelines for the land system innovations of small towns are put forward. Namely the sustainability of social and economic development, the balance between land reservation and land utilization, the provision of service to village, agriculture and farmer, the management of land resource and land assets, the parsimonious and legal use of land. The basic framework of land system innovations of small towns is put forward finally. It include the land replacement policy for small towns and the permanent tenancy of farmland, the overall plan for land uses and other plans in harmony, the establishment of a flexible system of land supplies, using land with payments, the transfer of agricultural land and refining the land law related to the construction of small towns.

Suitability Analysis of Satellite Towns Using Saaty Model and Geographical Information System (GIS)

Dar es Salaam is one of the fastest growing cities in East Africa, with a population of 4,364,541 whose annual growth rate is 4.5%. The population increase is mainly caused by rural to urban migration causing traffic congestion, unemployment, emerging of unplanned settlements, inadequate infrastructure, and social and housing services. In order to overcome these challenges there is an urgent need to establish and determine suitable locations of satellite towns to the outskirts of the central business district (CBD) to strengthen economic and social activities using reliable techniques. Selecting suitable locations of satellite towns has been determined by using distance from the CBD and population growth indicators. The limitations of using these indicators include unsuitable locations, which ultimately failed to attract economic growth in such areas. In this study, we introduce a new approach of selecting suitable location of satellite towns in fast growing cities. This approach uses Saaty Model and Geographic Information Systems techniques, whereby a pair wise comparison matrix, consistency index and consistency ratio are employed to determine suitable locations of satellite towns in Ubungo and Kinondoni Municipalities. Also, seven criteria were used to produce suitability maps for water, power line, road, communication line, elevation, slope and land use. The results obtained from this study show that about 5.31% of the area was classified as highly suitable, 29.82% as moderately suitable, 24.27% as marginally suitable and 40.6% permanently unsuitable. Locations of satellite towns determined using Saaty model was found to be on highly suitable areas whereas locations of satellite towns proposed by the Dar es Salaam master plan were located on marginally suitable areas. The study concludes that Saaty Model, if integrated with GIS, can be effectively used to determine suitable locations for satellite towns in urban areas.

Development of APEC Low-Carbon Town Indicator（LCT-I） System

The APEC （Asia-Pacific Economic Cooperation） LCMT （Low-Carbon Model Town） project was initiated in 2011 as apart of APEC＇s energy cooperation scheme in response to the rapid urbanization and growing fossil energy use in the developingeconomies of the APEC region. The LCMT project has conducted feasibility studies and policy reviews for a case town eachyear and developed and refined the ＂Concept of Low-Carbon Town in the APEC region （Concept）＂. The Concept is a guidebookfor city planners and developers who wish to implement low-carbon town design. In tandem with the Concept, the ＂APECLow-Carbon Town Indicator （LCT-I） System＂ has been developed since 2013. The LCT-I System is a self-assessment tool to assessand monitor the progress of each low-carbon town development project in the APEC region. The first edition of the LCT-I SystemGuideline and its evaluation sheet were published together with the final edition of the Concept in 2016. The LCMT project ismoving into the dissemination stage beginning in 2017 through the utilization of the LCT-I System. This paper explains the processof the development of the LCT-I System, provides a brief summary and discusses its expected role in the spread of low-carbontowns.

Relationship between electromagnetically-induced transparency and Autler–Townes splitting in a Doppler-broadened system

We study the relationship between electromagnetically-induced transparency（EIT） and Autler–Townes（AT） splitting in a cascade three-level Doppler-broadened system. By comparing the absorption spectrum with the fluorescence excitation spectrum, it is found that for a Doppler-broadened system, EIT resonance cannot be explained as the result of quantum interference, unlike the case of a homogeneously broadened system. Instead, the macroscopic polarization interference plays an important role in determining the spectra of EIT and AT splitting, which can be explained within the same framework when being detected by the absorption spectra.
