Land use has important effects to ecological environmental vulnerability. From the view of land use types, impacts of land use on ecological environmental vulnerability were analyzed and assessed in Kenli County of the Yellow River delta. Assessment index system including landscape structure and pattern, land use ecological applicability and land use stability was established. Remote sensing techniques were adopted to acquire land use information, expert marking method was used for index quantification, and AHP method was adopted for index weight determination. Based on these, the landscape structure and pattern index model, land use ecological applicability index model and land use stability index model were built up, and land use ecological environment vulnerability effect index model was established accordingly. Through assessment, land use ecological environment vulnerability effect index values in two scales of the whole county and town were gotten. Land use impacts on ecological environmental vulnerability and their spatial distribution were system analyzed. Based on the results, partitions of land use adjustment in Kenli County were proposed, and countermeasures of ecological construction in different areas were brought forward.
