and relations between the cultivated lands and landform in the areas of the middle and lower reaches of the Jialing River were analyzed
we also investigated spatiotemporal variation trend of cultivated land resources in the past 50 years.Results indicate the cultivated land area decreases abruptly after a long-term increase
but structure of the increased lands is unreasonable.So we must pay attention to both quantity and quality
which helps to the ecological environment construction
