To achieve sustainable development, detailed planning, control and management of land cover changes that occurs naturally or by human caused artificial factors, is essential. Urban managers and planners need a tool that represents them the information accurate, fast and in exact time. In this study, land use changes of 3 periods 1994-2002, 2002-2009, 2009-2015 and predictions of 2009, 2015 and 2023 were assessed. In this paper, Maximum Likelihood method was used to classify the images, so that after evaluation of accuracy, amount of overall accuracy for images of 2013 was 85.55 % and its Kappa coefficient was 80.03%. To predict land use changes, Markov-CA model was used that after assessing the accuracy, the amount of overall accuracy for 2009 was 82.57% and for 2015 was 93.865%. ThenWebGis application was designed via map server application and evoked shape files through map file and open layers to browser environment and for design of appearance of website Css, HTML and JavaScript languages were used.

Ecological Preservation

Land use and cover change (LUCC) is an important method to investigate the causes of global environment change. We utilized the emergy ecological footprint (EEF) model to construct a land-use change model to be used as a systematic measuring tool for monitoring sustainable development trends. In particular, we estimated the eco-security of the Cing-jing region as a case study so that responsible agencies can use it to maintain a balance between ecological preservation and tourism development. The results indicated the following: First, the ecological environment of the Cing-jing region satisfied the safety standard in 2008–2014; however, the related indices increased considerably. Second, the grey model predicted a decrease in 2015–2024 ecological carrying capacities of Cing-jing and a large increase in capita EFs, resulting in a larger ecological deficit and higher EFI. The eco-security from 2015–2024 was higher compared to 7 years ago and is predicted to reach the Grade 2 intermediate level in 2022; thus the Cing-jing region is gradually becoming ecologically unsustainable. Strengths of our study included the use of EEF theory in a quantitative analysis of slope lands for the effective evaluation of ecological security. Finally, we expanded our research to include ecological security issues.

Basic Prerequisite

In the context of the new urbanization, ensuring ecological security of land use is one of the most basic prerequisite for ecological civilization construction. This paper is based on the theory of ecological footprint, and use ecological pressure index to evaluate the state of land-use ecological security of Yiwu City, Zhejiang Province. The results indicate land ecological pressure indexes increasing from 2.5912 in 2008 to 2.8029 in 2012 are gradually on the rise in Yiwu City. The deterioration of land-use ecological security is exacerbating. Finally, suggestions improving ecological security of land use are proposed from arable land protection, energy saving, and ecological and environmental comprehensive management.
