Analysis of agricultural ecology and environment is based on the data of agricultural resources, which are obtained by
RS monitoring. The over-exploitation of farmlands will cause structural changes of the soil composition, and damage the
planting environment and the agro-ecosystem. Through the research on the dynamic monitoring methods of multitemporal
RS images and GIS technology, the crop growth status, crop acreage and other relevant information in
agricultural production are extracted based on the monitor and analysis of the conditions of the fields and crop growth.
The agro-ecological GIS platform is developed with the establishment of the agricultural resources management
database, which manages spatial data, RS data and attribute data of agricultural resources. Using the RS, GIS analysis
results, the reasons of agro-ecological destruction are analyzed and the evaluation methods are established. This paper
puts forward the concept of utilization capacity of farmland, which describes farmland space for development and
utilization that is influenced by the conditions of the land, water resources, climate, pesticides and chemical fertilizers
and many other agricultural production factors. Assessment model of agricultural land use capacity is constructed with
the help of Fuzzy. Assessing the utilization capacity of farmland can be helpful to agricultural production and ecological
protection of farmland. This paper describes the application of the capacity evaluation model with simulated data in two
aspects, namely, in evaluating the status of farmland development and utilization and in optimal planting.
