Ecological stoichiometry of science is the study of biological systems, energy
and chemical balance, is a study in biogeochemical cycles of elements [19], and
ecological processes in the integrated approach to metering and regulation [1].
Potassium is one of the three elements of the plant, is indispensable for a
large number of elements in the metabolic processes of plants. This article
reveals the potassium in plant leaves-chemical measurement characteristics and
spatial pattern of variation, using theories and methods of ecological
stoichiometry, on the determination of North China 37-point sampling, take
samples of hippophae rhamnoides and soil samples in the sample sites,
respectively. Sample digestion using H2SO4-H2O2, by flame photometer (BWB XP
Performance Plus, UK) determination of potassium element contents in leaves and
soil, and analyzed. Results showed that of the geometric mean in leaves of
Chinese seabuckthorn and potassium 11.76mg g − 1, the main factors affecting
geographic variables (including latitude, longitude, altitude), climatic
conditions (including: average annual temperature, with an average annual
rainfall) and soil potassium content. Potassium content in leaves of which
increase with altitude increase, with an average annual temperature of decreases
and increases, due to leaves of potassium from soil, soil potassium and
potassium content in leaves show a consistent trend, with longitude decline and
