With the intensification of human activities and unreasonable development and utilization of land resources, there have been a series ecological problems of land resources in Hubei Province. Based on the Press-State-Response conceptual framework model, this paper developed to build the ecological security assessment index system of the land resource which was regional characteristics, by the use of component analysis to determine the weight, the use of land resources ecological security comprehensive model, the land ecological security index of Hubei Province from 2000 to 2011 were calculated. The results showed that comprehensive land resources ecological security index increased from 0.646 to 0.7719 during 2000–2011, the land of ecological security was in a “risk stage” period in 2000, while in a “good level” in 2011. Although the ecological security assessment status was improved annually, the land ecological pressure was still seriously, per capita arable land, the natural population growth rate, population density, fertilizer application rate and other factors caused some damage to the ecological system, which need us to throw out some suggestions based on these factors. To reduce the pressure on the land resources and to enhance the ecological security of land resources, is to control population size and to improve the quality of existing population.

Urban heat island effect refers to the phenomenon of urban temperatures being higher than the suburban. relation of the city land use and the urban heat island effect has gradually become an important environmental problem that arousing general concern. Remote sensed data has been an effective measure monitoring and analyzing the land use change and the urban heat island effect. This paper adopted the maximum likelihood classification to divide the Guangzhou City land use types into cultivated land, forest, water, bare land and built-up using Landsat TM data 0f 1990, 1998 and 2005; The city heat island region was indicated by the urban brightness temperature, furthermore, the urban brightness temperature was retrieved by the band 6 of Landsat TM, the ground brightness temperature map was achieved. Based on GIS, this paper analyzed the relation of the urban heat island effect and the land use types in Guangzhou City. The aim of this paper is to provide the basic information for improving environmental quality and the rational land use pattern in Guangzhou City.
