In recent years, the land resource ecological problems become more and more serious. And the study on ecological security of land resources becomes the frontier problems on Sustainable Utilization of land resources. Based on P-S-R model, this paper built the land resource ecological security index system. And it studyed the land resource ecological security status of Chongqing city from 2001 to 2010.The results showed that land resources ecological security situation of Chongqing city has been improved in recent ten years, but the security situation is still not optimistic. It needs further take effective measures and improve the land resources ecological condition.

To provide a theoretical basis for sustainable land resource utilization and a reference for areas with similar natural conditions, an evaluation index for land-based ecological security was constructed based on the Driving force-Pressure-State-Impact-Response (DPSIR) model and the improved analytic hierarchy process (IAHP) and entropy methods, and the land-based ecological security status of Xingtai city from 2006 to 2017 was evaluated. Then, the obstacles to land-based ecological security were diagnosed. The results show that the values of the comprehensive evaluation index of land-based ecological security were 0.28–0.66 in the period from 2006 to 2017. The value of the index of land-based ecological security was low in the first seven years and gradually improved in the last five years of the study period. However, the overall situation was grave, and the ecological security conditions were poor. The main obstacles to land-based ecological security were the usage of pesticides, investment in environmental pollution treatments, the degree of machine cultivation, the rate of cultivation and the usage of fertilizer in Xingtai city. Based on the results of the land-based ecological security evaluation and the main obstacles identified in Xingtai city, this paper proposes management strategies and suggestions for improving land-based ecological security in Xingtai city. The specific proposals are as follows: vigorously develop green agriculture, increase investment in environmental pollution control, increase input in science and technology, and strengthen supervision and management of land use.

Land Ecological Security, the land ecological system which embraced various organic and inorganic above the surface of land is not damaged. Land Resource Ecological Security is a healthy or balanced status means the land resource is not or less threatens. From the two statements, both have similar meaning. The evaluation of the land ecological security is a meaningful and predictable evaluation which is about earth usage result of the macro-restructure and possible impact on environment and ecology, and which is guideline to keep the environment uninfluenced and district ecology safe from the earth usage planning. Based on summarizing the recent research domain, research target, research time, parameter of evaluation, and methods, this paper analyzed the new research progress.

Agustini S, Suparman S, Tridamayanti HC. 2020. Landuse planning for food crop areas development using land resource evaluation approach and gis application (a case study of Pulang Pisau District, Central Kalimantan Province). Jurnal Lahan Suboptimal: Journal of Suboptimal Lands  9(1): 64-72.In order to promote sustainable landuse, the need of landuse planning is urgently required and it can be designed based on the result of spatial land resource data management. Land resource evaluation is main component for landuse planning which this procedure was applied to determine land allocation for arable lands for rice farming development. The use of geographic information system (GIS) technology was also employed not only for spatial data management, but they could also be applied to support decision making within establishing landuse planning. The objective of this study was to allocate the arable lands for extensification and intensification regions as main part of landuse planning for food crops areas development.  In the case of Pulang Pisau District, land allocation for extensification and intensification regions were mainly found in southern part and mostly located at  watershed areas with each total areas respectively of 380,261 hectares (36.81%) and 29,941 hectares (2.90% of total areas of Pulang Pisau District). In order to support these potential areas, specific programs could then be formulated to increase the yield and productivity for these regions.
